(n, p, seed=None, fast=False)[source]¶ Return a random graph (Erdos-Renyi graph, binomial graph).
Chooses each of the possible edges with probability p.
Parameters: - n : int
The number of nodes.
- p : float
Probability for edge creation.
- seed : int, optional
Seed for random number generator (default=None).
- fast : boolean, optional
Uses the algorithm proposed by [3], which is faster for small p
