networkx.algorithms.community.modularity_max.greedy_modularity_communities¶

greedy_modularity_communities
(G, weight=None)[source]¶ Find communities in graph using ClausetNewmanMoore greedy modularity maximization. This method currently supports the Graph class and does not consider edge weights.
Greedy modularity maximization begins with each node in its own community and joins the pair of communities that most increases modularity until no such pair exists.
 Parameters
G (NetworkX graph)
 Returns
 Return type
Yields sets of nodes, one for each community.
Examples
>>> from networkx.algorithms.community import greedy_modularity_communities >>> G = nx.karate_club_graph() >>> c = list(greedy_modularity_communities(G)) >>> sorted(c[0]) [8, 14, 15, 18, 20, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33]
