WebHowever, as we argued, Even vertices can be matched only to Odd vertices. So, in any matching at least jXjvertices must be unmatched. The current matching has jXjunmatched vertices, so the current matching Mmust be optimal. 2 Corollary 8 If Gis bipartite and the algorithm nds a collection of maximal M-alternating trees, then Mis a maximal matching. WebA common bipartite graph matching algorithm is the Hungarian maximum matching algorithm, which finds a maximum matching by finding augmenting paths.More formally, the algorithm works by attempting to …
