random_regular_graph¶

random_regular_graph(d, n, seed=None)[source]¶

Return a random regular graph of n nodes each with degree d.

The resulting graph G has no self-loops or parallel edges.

Parameters:

d : int

Degree

n : integer

Number of nodes. The value of n*d must be even.

seed : hashable object

The seed for random number generator.

Notes

The nodes are numbered form 0 to n-1.

Kim and Vu’s paper [R318] shows that this algorithm samples in an asymptotically uniform way from the space of random graphs when d = O(n**(1/3-epsilon)).
