barabasi_albert_graph
(n, m, seed=None)[source]¶ Returns a random graph according to the Barabási–Albert preferential attachment model.
A graph of \(n\) nodes is grown by attaching new nodes each with \(m\) edges that are preferentially attached to existing nodes with high degree.
- Parameters
n (int) – Number of nodes
m (int) – Number of edges to attach from a new node to existing nodes
seed (integer, random_state, or None (default)) – Indicator of random number generation state. See Randomness.
- Returns
G
- Return type
- Raises
NetworkXError – If
m
does not satisfy1 <= m < n
