random_partition_graph(sizes, p_in, p_out, seed=None, directed=False)¶
Return the random partition graph with a partition of sizes.
A partition graph is a graph of communities with sizes defined by s in sizes. Nodes in the same group are connected with probability p_in and nodes of different groups are connected with probability p_out.
G – random partition graph of size sum(gs)
NetworkX Graph or DiGraph
NetworkXError– If p_in or p_out is not in [0,1]
>>> G = nx.random_partition_graph([10,10,10],.25,.01) >>> len(G) 30 >>> partition = G.graph['partition'] >>> len(partition) 3
This is a generalization of the planted-l-partition described in . It allows for the creation of groups of any size.
The partition is store as a graph attribute ‘partition’.
