networkx.algorithms.bipartite.generators.random_graph¶

random_graph(n, m, p, seed=None, directed=False)[source]¶

Returns a bipartite random graph.

This is a bipartite version of the binomial (Erdős-Rényi) graph. The graph is composed of two partitions. Set A has nodes 0 to (n - 1) and set B has nodes n to (n + m - 1).

Parameters

n (int) – The number of nodes in the first bipartite set.
m (int) – The number of nodes in the second bipartite set.
p (float) – Probability for edge creation.
seed (integer, random_state, or None (default)) – Indicator of random number generation state. See Randomness.
directed (bool, optional (default=False)) – If True return a directed graph

Notes

The bipartite random graph algorithm chooses each of the n*m (undirected) or 2*nm (directed) possible edges with probability p.

This algorithm is \(O(n+m)\) where \(m\) is the expected number of edges.

The nodes are assigned the attribute ‘bipartite’ with the value 0 or 1 to indicate which bipartite set the node belongs to.

This function is not imported in the main namespace. To use it use nx.bipartite.random_graph
