A perfect matching is also a minimum-size edge cover. Thus, the size of a maximum matching is no larger than the size of a minimum edge cover: . A graph can only contain a perfect matching when the graph has an even number of vertices. Meer weergeven In the mathematical discipline of graph theory, a matching or independent edge set in an undirected graph is a set of edges without common vertices. In other words, a subset of the edges is a matching if each vertex … Meer weergeven Given a graph G = (V, E), a matching M in G is a set of pairwise non-adjacent edges, none of which are loops; that is, no two edges share common vertices. A vertex is … Meer weergeven A generating function of the number of k-edge matchings in a graph is called a matching polynomial. Let G be a graph and mk be … Meer weergeven Kőnig's theorem states that, in bipartite graphs, the maximum matching is equal in size to the minimum vertex cover. Via this result, the minimum vertex cover, maximum independent set, and maximum vertex biclique problems may be solved in polynomial time Meer weergeven In any graph without isolated vertices, the sum of the matching number and the edge covering number equals the number of vertices.
