The algorithm is taken from "Efficient Algorithms for Finding Maximum Matching in Graphs" by Zvi Galil, ACM Computing Surveys, 1986. It is based on the "blossom" method for finding augmenting paths and the "primal-dual" method for finding a matching of maximum weight, both due to Jack Edmonds.
Some ideas came from "Implementation of algorithms for maximum matching on non-bipartite graphs" by H.J. Gabow, Standford Ph.D. thesis, 1973.
A C program for maximum weight matching by Ed Rothberg was used extensively to validate this new code.
