I use the following to iterate over all matchings and perfect matchings. def matchings(G): edges = G.edges(labels = False) verts = [[v] for v in G] m = len(edges) for match in DLXCPP(edges+verts): yield [edges[t] for t in match if t < m]
def perfect_matchings(G): edges = G.edges(labels = False) for match in DLXCPP(edges): yield [edges[t] for t in match] -- You received this message because you are subscribed to the Google Groups "sage-support" group.
