Hi Alessio,

You're correct - the BGL has an implementation of an algorithm to find
a maximum matching in an unweighted graph, but doesn't yet have a
maximum weighted matching algorithm, even for bipartite graphs. A
recent message on on the boost development mailing list had a link to
a C implementation of maximum weighted matching for graphs (not just
bipartite):

This is the only such free implementation I've seen.
