WebFinite graph infinite graph. Bipartite graphs: A bipartite graph, also called a bigraph, is a set of graph vertices decomposed into two disjoint sets such that no two graph vertices within the same set are adjacent. Incidence and Degree: When a vertex vi is an end vertex of some edge ej, vi and ej are said to incident with each other. WebFor a perfect matching the number of vertices in the complete graph must be even. For a complete graph with n vertices (where n is even), no of perfect matchings is n! ( 2!) n / 2 ( n / 2)! For n = 2 m, it is ( 2 m)! ( 2!) m m! Using this formula for n=6, the number of partitions = 15 Explanation: scandinavian movies online
