- 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).
The number of nodes in the first bipartite set.
The number of nodes in the second bipartite set.
Probability for edge creation.
- seedinteger, random_state, or None (default)
Indicator of random number generation state. See Randomness.
- directedbool, optional (default=False)
If True return a directed graph
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
