Edmonds matching

Web3 Edmonds’ cardinality matching algorithm The idea of shrinking the found blossom(s), finding an augmenting path if there is one and then expand the shrunken blossom(s) is the gist of the Edmonds’ matching algorithm (Lemma 2.). While trying to find an augmenting path an alternating forest will be built up. WebJun 19, 2024 · Edmonds (1961) have proposed the Blossom algorithm to solve the maximum matching problem for undirected graphs. The best implementation of it is due to Micali and Vazirani (1980): O ( E V ) time. There is a version of the Blossom algorithm for weighted graphs ( Kolmogorov, 2009 ), but still it concerns only undirected graphs.

WebA maximum matching (also known as maximum-cardinality matching [2]) is a matching that contains the largest possible number of edges. There may be many maximum matchings. The matching number of a graph G is the size of a maximum matching. Every maximum matching is maximal, but not every maximal matching is a maximum matching.
