networkx.generators.community.caveman_graph

caveman_graph(l, k)[source]

Returns a caveman graph of l cliques of size k.

Parameters:
  • l (int) – Number of cliques
  • k (int) – Size of cliques
Returns:

G – caveman graph

Return type:

NetworkX Graph

Notes

This returns an undirected graph, it can be converted to a directed graph using nx.to_directed(), or a multigraph using nx.MultiGraph(nx.caveman_graph(l, k)). Only the undirected version is described in [1] and it is unclear which of the directed generalizations is most useful.

Examples

>>> G = nx.caveman_graph(3, 3)
