+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ ** CHKLREF README **
+
+
+I. Installation
+---------------
+
+ I.1. System wide installation
+ -----------------------------
+
+ You need the root privileges to perform this installation
+
+ Simply run
+
+ ./configure
+ make
+ sudo make install
+
+ This package follows the TDS[1] and installs:
+ * the main program in $(prefix)
+ * the TeX package chklref.sty in $(texmf_prefix)/tex/latex/chklref
+ * the manual chklref.pdf in $(texmf_prefix)/doc/latex/chklref
+ * the Perl parser chkparser in $(texmf_prefix)/scripts/chklref
+
+ The following default values are used
+ * prefix=/usr/local
+ * texmf_prefix=$(prefix)/share/texmf
+
+ These default values can be changed with the flags --prefix
+ and --with-texmf-prefix passed to the configure script.
+
+ Note: Do not forget to run "sudo texhash" to update your TeX Directory
+ ----
+ Structure.
+
+ Notes for installation under MacOS X:
+ ------------------------------------
+
+ Under MacOS X, your tex distribution is probably not installed under
+ /usr/share/texmf nor /usr/local/share/texmf. You are most likely using
+ the TeXlive distribution provided by MacTeX which installs under
+ /usr/local/texlive. Hence, you should invoke configure with
+
+ --with-texmf-prefix=/usr/local/texlive/texmf-local
+
+
+ I.2. Installation on a single account
+ -------------------------------------
+
+
+ This installation does not require any particular privileges.
+
+ We assume that the directory $HOME/bin is in your PATH, if not you have to
+ add it your PATH. You can install the software on your account using
+
+ ./configure --prefix=$HOME --with-texmf-prefix=$HOME/texmf
+ make
+ make install
+
+ Note: For the installation on a single account, there is no need to run
+ ----
+ texhash.
+
+ Notes for installation under MacOS X:
+ ------------------------------------
+
+ The directory $HOME/texmf may not exist because it is replaced by
+ $HOME/Library/texmf instead. So, either use
+
+ ./configure --prefix=$HOME --with-texmf-prefix=$HOME/Library/texmf
+
+ or create a symbolic link
+
+ ln -s $HOME/Library/texmf $HOME/texmf
+
+
+2. Execution
+------------
+
+ Just run: chklref texfile
+
+ To run ckhlref, you need a Perl interpreter. As no special Perl
+ packages are needed, a very basic Perl distribution should be ok.

+\`configure' configures chklref 2.5.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+\begin{document}
+\maketitle
+
+\begin{abstract} Which \LaTeX\ user has never dreamt of cleaning its \TeX\ file
+ of any useless labels right before submitting an article for instance? This is
+ precisely what \chk\ will help you achieve.
+\end{abstract}
+
+\section{What {\it chklref} can do for a \LaTeX\ user ?}
+
+While writing a \LaTeX document, it is quite common to add labels that will
+reveal unused in the end, this is especially true for equations or any other
+mathematical environments. It would be quite convenient to wipe out those labels
+from the final version of the document. \chk\ has been designed to help any
+\TeX\ user do so.
+
+\chk\ parses the \LaTeX\ file to detect labels that do not have any matching
+reference. At the end of the program, a summary is printed with the list of
+labels to be removed. Obviously, this search is performed in the whole document
+and not only within mathematical environments. Nonetheless, there is something
+specifically dedicated to environments that have a star version: it looks
+for the non star environments not containing any label.
+
+For instance, consider you a have a \LaTeX\ file with the following piece of code
+\begin{verbatim}
+\begin{equation}
+ x^2 + x + 1 = 0
+\end{equation}
+\end{verbatim}
+\chk\ will advise you to consider using \verb!equation*! instead of
+\verb!equation! in order to remove the unneeded number appearing next to the
+equation.
+
+Star environments with labels are also tracked because with most \LaTeX\
+distributions it does not even raise a warning. However in case you may refer to
+this label the number that would appear is likely to be nonsense.
+
+The summary printed at the end of the program contains two sections (see
+Figure~\ref{fig:output}): one is about labels in star environments and one is about
+unneeded labels. Each of these output lines begins with a line number referring
+to the parsed \LaTeX\ file. Then, the decision to be made is printed:
+``remove label'' or ``use a starred environment''. In the case of a ``remove
+label'' message, the label to be removed is also printed to avoid any possible
+confusion.
+

+line 313 : remove label eq:prog_dyn_prix
+\end{verbatim}
+ \caption{Program output}
+ \label{fig:output}
+\end{figure}
+
+Since version 2.5, the checking of bibliography entries has been added to detect
+if some entries are not explicitly cited in the text, see
+Figure~\ref{fig:output}. In this case, a ``remove bibitem'' message is printed.

+\section{Usage}
+
+Typical usage : \verb!chklref file.tex!.
+\\
+
+\section{Installation}
+
+
+\subsection{System wide installation}
+
+You need the root privileges to perform this installation. \\
+
+\noindent Simply run
+
+\begin{verbatim}
+ ./configure
+ make
+ sudo make install
+\end{verbatim}
+This package follows the TDS\footnote{TeX Directory Structure
+ \url{http://www.tug.org/twg/tds/}} and installs:
+\begin{itemize}
+ \item the main program in \verb!$(prefix)!
+ \item the \TeX\ package \verb!chklref.sty! in \verb!$(texmf_prefix)/tex/latex/chklref!
+ \item the manual \verb!chklref.pdf! in \verb!$(texmf_prefix)/doc/latex/chklref!
+ \item the Perl parser \verb!chkparser! in \verb!$(texmf_prefix)/scripts/chklref!
+\end{itemize}
+The following default values are used
+\begin{itemize}
+ \item \verb!prefix=/usr/local!
+ \item \verb!texmf_prefix=$(prefix)/share/texmf!
+\end{itemize}
+
+These default values can be changed with the flags \verb!--prefix! and
+\verb!--with-texmf-prefix! passed to the configure script.\\
+
+Do not forget to run "sudo texhash" to update your \TeX\ Directory Structure.
+
+\paragraph{Notes for installation under MacOS X.}
+
+Under MacOS X, your tex distribution is probably not installed under
+\verb!/usr/share/texmf! nor \verb!/usr/local/share/texmf!. You are most likely using
+the TeXlive distribution provided by MacTeX which installs under
+\verb!/usr/local/texlive!. Hence, you should invoke configure with
+
+\begin{verbatim}
+ --with-texmf-prefix=/usr/local/texlive/texmf-local
+\end{verbatim}
+
+\subsection{Installation on a single account}
+
+This installation does not require any particular privileges.
+
+We assume that the directory \verb!$HOME/bin! is in your PATH, if not you have to add it
+your PATH. You can install the software on your account using
+\begin{verbatim}
+ ./configure --prefix=$HOME --with-texmf-prefix=$HOME/texmf
+ make
+ make install
+\end{verbatim}
+For the installation on a single account, there is \emph{no} need to run
+texhash.
+
+
+\paragraph{Notes for installation under MacOS X.}
+
+The directory \verb!$HOME/texmf! may not exist because it is replaced by
+\verb!$HOME/Library/texmf! instead. So, either use
+\begin{verbatim}
+ ./configure --prefix=$HOME --with-texmf-prefix=$HOME/Library/texmf
+\end{verbatim}
+or create a symbolic link
+\begin{verbatim}
+ ln -s $HOME/Library/texmf $HOME/texmf
+\end{verbatim}
+
+
+
+\section{Requirements}
+
+\chk\ is written mainly in \TeX\ with a small Perl script to parser the output
+generated by the \TeX\ package. It should be working with any standard Perl
+installation.
+
+\section{Source code}
+
+The source code is available from GitHub
+\url{https://github.com/jlelong/chklref}.
+\\
+
+\noindent It is distributed under the GPL licence version 3 or any later version
+in the hope it will be useful but without any warranty. Should you find a bug in
+chklref, send me a mail to \verb!jerome.lelong@gmail.com! describing the problem
+with a minimal \LaTeX\ file to reproduce the problem or fill in an issue on the
+GitHub repository.

+\section{Méthodes d'arbre pour les options américaines}
+
+On proposer de calculer le prix du put américain dans un modèle d'arbre.
+\begin{itemize}
+\item Implémenter la résolution de l'équation de programmation dynamique dans un
+ modèle d'arbre.
+\item Comparer les résultats pour les modèles de Cox Ross Rubinstein et de
+ Kamrad Ritchken
+\item Etudier la vitesse de convergence quand le pas de l'arbre tend vers $0$.
+\end{itemize}
+
+
+\section{Inéquation aux dérivées partielles pour les options américaines}
+
+
+On se propose de calculer le prix du put américain dans le modèle de Black
+Scholes en résolvant l'inéquation aux dérivées partielles satisfaites par sa
+fonction prix.
+
+\subsection{Formulation du problème}
+
+
+On considère l'opérateur elliptique $A$ défini par
+\begin{equation*}
+ \cl = \frac{\sigma^2}{2} \frac{\partial^2}{\partial x^2} + \left(r -
+ \frac{\sigma^2}{2}\right) \frac{\partial}{\partial x} -r
+\end{equation*}
+où $r$ et $\sigma$ sont deux constantes réelles.
+On se donne une fonction $f : \R \longrightarrow \R_+$, un ouvert $\co_l = ]-l, l[$
+et on cherche à résoudre le problème suivant
+\begin{equation}
+ \label{eq:ineq_diff}
+ \tag{$E$}
+ \left\{
+ \begin{array}{l}
+ \dpart{v}{t}(t,x) + \cl v(t,x) \leq 0 \quad \mbox{dans $[0,T] \times \co_l$}\\
+ v(t,x) \geq f(x)\\
+ (v(t,x) - f(x)) \left(\dpart{v}{t}(t,x) + \cl v(t,x)\right) = 0 \quad \mbox{dans $[0,T]
+ \times \co_l$}\\
+ v(T,x) = f(x)\\
+ \dpart{v}{x}(t, \pm l) = 0.
+ \end{array}
+ \right.
+\end{equation}
+
+Soit $v(t, y)$ le prix à l'instant $t$ du put américain dans le modèle de
+Black Scholes si le sous-jacent vaut $\expp{y}$. La fonction $v$ est solution du
+système~\ref{eq:ineq_diff} avec $l=\infty$ et $f(x) = (K - \expp{x})_+$.
+
+\subsection{Méthode de résolution}
+\subsubsection{discrétisation du système d'inéquations}
+
+Nous allons maintenant voir comment résoudre le système~(\ref{eq:ineq_diff}) par une
+méthode numérique. On se propose d'utiliser une méthode de différences finies pour
+discrétiser le système à la fois en temps et en espace.
+
+Soit $N \in \N^*$, on note $h = \frac{2l}{N+1}$ et $x_i = -l + ih$ pour $0 \leq i
+\leq N+1$. On définit le vecteur $f_h$ par $f_h^i=f(x_i)$.
+
+Pour toute fonction $u: \co_l \longrightarrow \R$, on adopte la notation $u_h =
+{(u_h^i)}_{1 \leq i \leq N} = {(u(x_i))}_{1 \leq i \leq N}$. On considère la
+discrétisation de l'opérateur $\cl$ suivante
+\begin{equation*}
+ (\cl_h u_h)_i = \frac{\sigma^2}{2h^2} (u_h^{i+1} - 2 u_h^i + u_h^{i-1}) + \left(r -
+ \frac{\sigma^2}{2}\right) \frac{1}{2h} (u_h^{i+1} - u_h^{i-1}) -r u_h^i
+\end{equation*}
+L'opérateur $\cl_h$ peut donc être représenté par la matrice tridiagonale suivant
+\[
+\cl_h =
+\begin{pmatrix}
+ \beta & \gamma & 0 & \dots & 0 & 0 \\
+ \alpha & \beta & \gamma & 0 & \dots & 0 \\
+ 0 & \alpha & \beta & \gamma & \dots & 0 \\
+ 0 & \vdots & \ddots & \ddots & \ddots & \vdots \\
+ 0 & 0 & \dots & \alpha & \beta & \gamma \\
+ 0 & 0 & 0 & \dots & \alpha & \beta
+\end{pmatrix}
+\]
+avec
+\[
+\begin{cases}
+ \alpha = & \frac{\sigma^2}{2 h^2} - \frac{1}{2h} \left(r -
+ \frac{\sigma^2}{2} \right), \\
+ \beta = & -\frac{\sigma^2}{h^2} - r, \\
+ \gamma = & \frac{\sigma^2}{2 h^2} + \frac{1}{2h} \left(r -
+ \frac{\sigma^2}{2}\right).
+\end{cases}
+\]
+Une fois cette discrétisation en espace effectuée, on se ramène à une équation
+différentielle ordinaire ne portant que sur le temps
+\begin{equation}
+ \label{eq:ineq_diff_h}\tag{$E_h$}
+ \begin{cases}
+ \displaystyle \d{u_h}{t}(t) + \cl_h u_h(t) \leq 0 \quad \forall t \in
+ [0,T],\\
+ u_h(t) \geq f_h\\
+ (u_h(t) - f) \left(\d{u_h}{t}(t) + \cl_h u_h(t)\right) = 0 \quad \mbox{dans
+ $[0,T]$}\\
+ u_h(T) = f_h\\
+ \d{v}{x}(t, \pm l) = 0.
+ \end{cases}
+\end{equation}
+Si $x$ et $y$ sont deux vecteurs de $\R^d$, on note $x \leq y$ pour $x_i \leq y_i
+\; \forall 1 \leq i \leq d$. Il ne reste plus alors qu'à discrétiser
+l'équation~(\ref{eq:ineq_diff_h}) grâce à des $\theta-$schémas. On note $k =
+\frac{T}{M}$ le pas de discrétisation en temps. On approche alors la solution $u_h$
+de~(\ref{eq:ineq_diff_h}) à l'instant $mk$ par $u_{h,k}^m$ défini par
+\begin{equation}
+ \label{eq:sys_discre_k_h}\tag{$E_{h,k}$}
+ \begin{cases}
+ u_{h,k}^M = f_h, \\
+ \mbox{Et pour $0 \leq m \leq M-1$}\\
+ u_{h,k}^m \geq f_h \\
+ u_{h,k}^{m+1} - u_{h,k}^m + k (\theta \cl_h u_{h,k}^m + (1 -
+ \theta) \cl_h u_{h,k}^{m+1}) \leq 0 \\
+ \left(u_{h,k}^{m+1} - u_{h,k}^m + k (\theta \cl_h u_{h,k}^m + (1 -
+ \theta) \cl_h u_{h,k}^{m+1}) , u_{h,k}^m - f_h\right) = 0
+ \end{cases}
+\end{equation}
+où $(x,y)$ est le produit scalaire de $\R^N$.
+
+En introduisant les notations matricielles suivantes
+\begin{equation*}
+ \begin{cases}
+ T = & I - k\theta \cl_h\\
+ G = & \left(I + k(1-\theta) \cl_h\right) u_{h,k}^{m+1}\\
+ M = & \left(I + k(1-\theta) \cl_h\right)
+ \end{cases}
+\end{equation*}
+le système~(\ref{eq:sys_discre_k_h}) se réécrit
+\begin{equation*}
+ \begin{cases}
+ T u_{h,k}^m - M u_{h,k}^{m+1} & \geq 0 \\
+ u_{h,k}^m - u_{h,k}^M & \geq 0\\
+ \tr{(T u_{h,k}^m - M u_{h,k}^{m+1})} (u_{h,k}^m - u_{h,k}^M) & = 0.
+ \end{cases}
+\end{equation*}
+La matrice $T$ est tridiagonale
+\[
+T =
+\begin{pmatrix}
+ a + b & c & 0 & \dots & 0 & 0 \\
+ a & b & c & 0 & \dots & 0 \\
+ 0 & a & b & c & \dots & 0 \\
+ 0 & \vdots & \ddots & \ddots & \ddots & \vdots \\
+ 0 & 0 & \dots & a & b & c \\
+ 0 & 0 & 0 & \dots & a & b+c
+\end{pmatrix}
+\]
+avec
+\[
+\begin{pmatrix}
+ a & = & \theta k \left( -\frac{\sigma^2}{2 h^2} + \frac{1}{2h} \left(r -
+ \frac{\sigma^2}{2} \right) \right) \\
+ b & = & 1 + \theta k \left(\frac{\sigma^2}{h^2} + r\right) \\
+ c & = & - \theta k \left( \frac{\sigma^2}{2 h^2} + \frac{1}{2h} \left(r -
+ \frac{\sigma^2}{2} \right) \right).
+\end{pmatrix}
+\]
+A chaque pas $m$ de $M-1$ à $1$, il s'agit de résoudre un système d'inéquations linéaires
+
+
+\subsubsection{algorithme de résolution}
+
+Il existe plusieurs algorithmes permettant de résoudre un tel système d'inéquations
+linéaires. On propose ici d'utiliser la méthode dite par troncature.
+\begin{algo}
+ Pour $m$ variant de $M-1$ à $1$, on résout
+ \begin{equation*}
+ T x = M u_{h,k}^{m+1},
+ \end{equation*}
+ puis on pose
+ \begin{equation*}
+ u_{h,k}^m = \max(x, f_h).
+ \end{equation*}
+\end{algo}
+Pour assurer la convergence de l'algorithme ci-dessus, on veillera à ce que les paramètres
+vérifient les conditions suivantes

+ \abs{r -\frac{\sigma^2}{2}} \leq \frac{\sigma^2}{h} \quad \mbox{et} \quad
+ \frac{k}{2h} \abs{r -\frac{\sigma^2}{2}} < 1.
+\end{equation*}
+Ces conditions assurent que la matrice $T$ est coercive (c.à.d $\tr{x}Tx \leq c
+\tr{x}x$ avec $c>0$).

+\subsection{Travail demandé}
+
+\begin{itemize}
+\item Résoudre le système~\eqref{eq:ineq_diff} par la méthode détaillée
+ ci-dessus.
+\item Dans la résolution du système linéaire, on s''efforcera de tirer profit
+ dans la structure tribande de la matrice en utilisant une décomposition de
+ type $Q = LU$, avec $L$ triangulaire inférieure et $U$ triangulaire. Ainsi le
+ système $Qx = b$ se résout en 2 étapes $Ly=b$ puis $Ux =y$.
+\item On s'intéressa aux cas $\theta=0$, $\theta=1/2$ et $\theta=1$. Comparer la
+ convergence pour ces différentes valeurs.
+\end{itemize}
+
+\section{Méthode de Monte Carlo pour les options américaines}
+
+On se propose de calculer le prix du put américain dans le modèle de Black
+Scholes par une méthode de Monte Carlo.
+
+\subsubsection*{Travail demandé}
+\begin{itemize}
+\item Il s'agit d'implémenter l'algorithme de
+ Longstaff et Schwartz en dimension $1$.
+
+ Pour la partie régression de l'algorithme, on pourra par exemple utiliser la
+ base canonique des polynômes de degré inférieur à $n$ $(x^d, 0 \le d \le n)$. On
+ pourra également ajouter à cette famille libre la fonction de payoff elle-même.
+
+\item Etudier la convergence en fonction du nombre de pas de temps, du nombre de
+ fonctions de base et de nombre de tirages Monte Carlo.

+\section{Options d'échange}
+
+\subsubsection*{Définition du modèle}
+
+On considère un modèle de \BS\ en dimension $2$. On pose $S_{t}=\left(S_{t}^{1},
+ S_{t}^{2}\right)$ le vecteur des cours des actifs. Soit $\left(W_{t}^1,
+ W_t^2\right)_{t\ge 0}$ $2$ mouvements Browniens standards de matrice de
+corrélation $\Gamma = \begin{pmatrix}
+ 1 & \rho \\
+ \rho & 1
+\end{pmatrix}$, avec $-1 < \rho < 1$ et de racine carrée $L$, obtenue par
+factorisation de Cholesky par exemple. Soit $r$ le taux d'intérêt (supposé
+constant), $\sigma = (\sigma_1, \dots, \sigma_d)$ le vecteur des volatilités et
+$S_{0}:=\left(S_{0}^{1},S_{0}^{2}\right)$ le vecteur des valeurs initiales des
+actifs (supposées déterministes). La dynamique du cours de l'actif $i$ est
+donnée par
+\begin{equation}
+ \label{eq:dS_u_v}
+ dS_{t}^{i}=S_{t}^{i}\left(r\,dt + \sigma_{i} \, d W_t^i\right),
+\end{equation}
+ou de manière équivalente par
+\begin{equation*}
+ dS_{t}^{i}=S_{t}^{i}\left(r \,dt + \sigma_{i} \,L_i d B_t\right),
+\end{equation*}
+avec $B$ un M.B en dimension $2$ et $L_i$ la $i^{eme}-$ligne de la
+matrice $L$. On note $\cf=\sigma(W)=\sigma(B)$.
+
+On souhaite calculer le prix de l'option d'échange de payoff $(S_T^1 - S_T^2)_+$
+donné par
+\begin{equation}
+ \label{eq:prix_echange}
+ \expp{-r T} \espbracket{(S_T^1 - S_T^2)_+}.
+\end{equation}
+
+\subsubsection*{Travail demandé}
+
+\begin{itemize}
+\item Donner une formule fermée pour le prix~\eqref{eq:prix_echange}.
+\item Implémenter la calcul de \eqref{eq:prix_echange} par une méthode de Monte
+ Carlo classique.
+\item Implémenter la calcul de \eqref{eq:prix_echange} par une méthode de Monte
+ Carlo utilisant une technique de réduction de variance basée sur le conditionnement.
+\item Comparer les variances empiriques obtenues pour chacun des deux estimateurs.
+\end{itemize}
+
+
+\section{Pricing des options asiatiques par méthode de Monte Carlo et méthodes
+ d'arbre}
+
+On s'intéresse au pricing du call asiatique à strike fixe de payoff
+\begin{align*}
+ \left(\frac{1}{T}\int_0^T S_u du -K\right)_+
+\end{align*}
+dans le modèle de Black Scholes
+\begin{itemize}
+\item Implémenter une méthode de Monte Carlo simple pour évaluer le prix du call
+ asiatique
+ \begin{equation}
+ \label{eq:prix_asiatique}
+ C=\espbracket{e^{-rT}\left(\frac{1}{T}\int_0^T S_u du -K\right)_+}.
+ \end{equation}
+\item Implémenter la technique de réduction de variance de Kemna et Vorst vue
+ dans le cours MAE51.
+\item Implémenter le calcul du prix dans le modèle d'arbre CRR. On approche le
+ sous-jacent $S$ par l'arbre binômial à $N$ pas de temps suivant
+ \begin{align*}
+ S_{n+1}=\left\{
+ \begin{array}{cl}
+ S_n e^{\sigma \sqrt{h}} & \mbox{avec probabilité }p\\
+ S_n e^{-\sigma \sqrt{h}} & \mbox{avec probabilité }1-p
+ \end{array}\right.
+ \end{align*} où $h=\frac{T}{N}$ et $p=\frac{e^{\sigma
+ \sqrt{h}}-e^{rh}}{e^{\sigma \sqrt{h}}-e^{-\sigma \sqrt{h}}}$. On approche
+ $C$ défini par l'équation~\eqref{eq:prix_asiatique} par
+ \begin{align*}
+ C^N_0=(1+R)^{-N}\espbracket{\frac{1}{N}\left(\sum_{j=1}^{N-1}
+ S_j+\frac{S_0+S_N}{2}\right)},
+ \end{align*}
+ où $R$ est tel que $1+R=e^{rh}$.
+ On rappelle que $C^N_n$, le prix du call asiatique à l'instant $n$, peut
+ s'écrire comme $C^N_n(n,S_0,\cdots,S_n)$. On rappelle aussi que puisque le
+ prix actualisé de l'option est une martingale, on a
+ \begin{align*}
+ C^N_n(n,S_0,\cdots,S_n)=\frac{1}{1+R}&\left(p
+ C^N_{n+1}(n+1,S_0,\cdots,S_n,S_ne^{-\sigma \sqrt{h}})\right.\\
+ &\left.+(1-p)C^N_{n+1}(n+1,S_0,\cdots,S_n,S_ne^{\sigma \sqrt{h}})\right).
+ \end{align*}
+ On notera $\displaystyle I_n=\frac{1}{n}\left(\sum_{j=1}^{n-1}
+ S_j+\frac{S_0+S_n}{2}\right)$ la valeur approchée de l'intégrale
+ $\displaystyle\frac{1}{nh}\int_0^{nh} S_u du$, et on montrera que
+ \begin{align*}
+ I_{n+1}=\frac{n}{n+1}I_n+\frac{S_n+S_{n+1}}{2}.
+ \end{align*}
+\item Comparer les 3 méthodes.
+\end{itemize}
+
+\section{Pricing des options barrières par formule fermée et par ponts
+ Browniens}
+
+On considère une option barrière call down and In dans le modèle de
+Black Scholes, c'est à dire de payoff
+
+
+\input{test22.tex}
+
+\begin{align}
+ (S_T-K)_+\ind{\exists u \le T \,:\, S_u \le L}.
+\end{align}
+
+
+\begin{itemize}
+\item En utilisant la loi du couple $(W_T,\inf_{u\le T} W_u)$ rappelée en annexe
+ donner une formule fermée pour le prix du Call Down and In.
+\item Implémenter une méthode de Monte Carlo pour calculer le prix.
+\item Utiliser les ponts Browniens pour estimer la probabilité de franchement de
+ la barrière entre deux instants de discrétisation et implémenter la méthode de
+ Monte Carlo améliorée ainsi obtenue.
+\end{itemize}
