- planted_partition_graph(l, k, p_in, p_out, seed=None, directed=False)¶
Returns the planted l-partition graph.
This model partitions a graph with n=l*k vertices in l groups with k vertices each. Vertices of the same group are linked with a probability p_in, and vertices of different groups are linked with probability p_out.
Number of groups
Number of vertices in each group
probability of connecting vertices within a group
probability of connected vertices between groups
- seedinteger, random_state, or None (default)
Indicator of random number generation state. See Randomness.
- directedbool,optional (default=False)
If True return a directed graph
