Problem Statement Let G (U ,V,E) be a bipartite graph on 2n … WebOne of the classical combinatorial optimization problems is finding a maximum matching in a bipartite graph. The bipartite matching problem enjoys numerous practical applications [2, Section 12.2], and many efficient, polynomial time algorithms for computing solutions [8] [12] [14]. Formally, a bipartite graph is a graphG= (U [V;E) in whichE µ U £V. 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. greft twitch
