Then, + the algorithm works just the way that a normal breadth first + search is performed: We keep a queue of to-be-visited nodes and + while this queue is not empty, we remove its first node. If this + node has not yet been visited, we add all its neighbors at the + end of the queue. When a node is taken out of the queue, we make + it the child of the node whose neighbor it was when it was + added. Since the queue follows the ``first in, first out'' + principle (it is a fifo queue), the children of the root will be + all nodes at distance $1$ form the root, their children will be + all nodes at distance $2$, and so on. + \item Now suppose that some edges have a priority different + from~1, in which case things get more complicated. We now keep + track of one fifo queue for each of the ten possible + priorities. When we consider the neighbors of a node, we actually + consider all its incident edges. Each of these edges has a certain + priority and the neighbor is put into the queue of the edge's + priority. Now, we still remove nodes normally from the queue for + priority~1; only if this queue is empty and there is still a node + in the queue for priority~2 we remove the first element from this + queue (and proceed as before). If the second queue is also empty, + we try the third, and so on up to the tenth queue. If all queues + are empty, the algorithm stops. + \end{enumerate} + + The effect of the ten queues is the following: If the edges of + priority $1$ span the whole graph, a spanning tree consisting solely + of these edges will be computed. However, if they do not, once we + have visited reachable using only priority 1 edges, we will extend + the spanning tree using a priority 2 edge; but then we once switch + back to using only priority 1 edges. If neither priority~1 nor + priority~2 edges suffice to cover the whole graph, priority~3 edges + are used, and so on.
