Web8 jun. 2008 · A perfect matching is a matching which covers all vertices. With respect to a weighted graph, a maximum weight matching is a matching for which the sum of the weights of the matched edges is as large as possible. In the depicted graph, a matching of weight 15 can be found by pairing vertex b to vertex c and vertex d to vertex e (leaving ... WebThis method is based on the “blossom” method for finding augmenting paths and the “primal-dual” method for finding a matching of maximum weight, both methods invented by Jack Edmonds [1]. Bipartite graphs can also be matched using the functions present in networkx.algorithms.bipartite.matching. References [ 1]
