graphscope.nx.generators.community.connected_caveman_graph

graphscope.nx.generators.community.connected_caveman_graph(l, k)

Returns a connected caveman graph of l cliques of size k.

The connected caveman graph is formed by creating n cliques of size k, then a single edge in each clique is rewired to a node in an adjacent clique.

Parameters:

• l (int) – number of cliques

• k (int) – size of cliques (k at least 2 or NetworkXError is raised)

Returns:

G – connected caveman graph

Return type:

NetworkX Graph

Raises:

NetworkXError – If the size of cliques k is smaller than 2.

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.connected_caveman_graph(3, 3)
