# networkx.algorithms.bipartite.cluster.robins_alexander_clustering¶

robins_alexander_clustering(G)[source]

Compute the bipartite clustering of G.

Robins and Alexander [1] 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
Ggraph

a bipartite graph

Returns
clusteringfloat

The Robins and Alexander bipartite clustering for the input graph.
