I have a random sample of graph algorithms implemented in
I use the existing Guido-standard graph representation, that is:
iter(G) and iter(G[v]) list vertices of G and neighbors of v in G
v in G and w in G[v] test existence of vertices and edges in G
It includes both simple basic graph algorithm stuff (copying a graph, a
DFS implementation that works non-recursively so it doesn't run into
Python's recursion limit) and some much more advanced algorithms (e.g.
non-bipartite maximum matching).
