Counting bipartite graphs

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: WebJun 27, 2014 · Abstract: Rectangles are the smallest cycles (i.e., cycles of length 4) and most elementary sub-structures in a bipartite graph. Similar to triangle counting in uni-partite graphs, rectangle counting has many important applications where data is modeled as bipartite graphs. However, efficient algorithms for rectangle counting are lacking.
