density¶

density(B, nodes)[source]¶

Returns density of bipartite graph B.

Parameters

BNetworkX graph
nodes: list or container: Nodes in one node set of the bipartite graph.

Returns

dfloat: The bipartite density

color

Notes

The container of nodes passed as argument must contain all nodes in one of the two bipartite node sets to avoid ambiguity in the case of disconnected graphs. See bipartite documentation for further details on how bipartite graphs are handled in NetworkX.

Examples

>>> from networkx.algorithms import bipartite
>>> G = nx.complete_bipartite_graph(3, 2)
>>> X = set([0, 1, 2])
>>> bipartite.density(G, X)
1.0
>>> Y = set([3, 4])
>>> bipartite.density(G, Y)
1.0
