robins_alexander_clustering¶

robins_alexander_clustering(G)[source]¶

Compute the bipartite clustering of G.

Robins and Alexander [R163] defined bipartite clustering coefficient as four times the number of four cycles \(C_4\) divided by the number of three paths \(L_3\) in a bipartite graph:

\[CC_4 = \frac{4 * C_4}{L_3}\]

Parameters:	G : graph a bipartite graph
Returns:	clustering : float The Robins and Alexander bipartite clustering for the input graph.
