preferential_attachment_graph

preferential_attachment_graph(aseq, p, create_using=None, seed=None)

Create a bipartite graph with a preferential attachment model from a given single degree sequence.

The graph is composed of two partitions. Set A has nodes 0 to (len(aseq) - 1) and set B has nodes starting with node len(aseq). The number of nodes in set B is random.

Parameters:

aseqlist

Degree sequence for node set A.

pfloat

Probability that a new bottom node is added.

create_usingNetworkX graph instance, optional

Return graph of this type.

seedinteger, random_state, or None (default)

Indicator of random number generation state. See Randomness.

Notes

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.preferential_attachment_graph
