networkx.generators.random_graphs.dense_gnm_random_graph

dense_gnm_random_graph(n, m, seed=None)

Returns a \(G_{n,m}\) random graph.

In the \(G_{n,m}\) model, a graph is chosen uniformly at random from the set of all graphs with \(n\) nodes and \(m\) edges.

This algorithm should be faster than gnm_random_graph() for dense graphs.

Parameters

• n (int) – The number of nodes.

• m (int) – The number of edges.

• seed (integer, random_state, or None (default)) – Indicator of random number generation state. See Randomness.
