cdlib.algorithms.greedy_modularity¶
- cdlib.algorithms.greedy_modularity(g_original: object, weight: list | None = None) NodeClustering ¶
The CNM algorithm uses the modularity to find the communities strcutures. At every step of the algorithm two communities that contribute maximum positive value to global modularity are merged.
Supported Graph Types
Undirected
Directed
Weighted
Yes
No
No
- Parameters:
g_original – a networkx/igraph object
weight – list of double, or edge attribute Weights of edges. Can be either an iterable or an edge attribute. Deafault None
- Returns:
NodeClustering object
- Example:
>>> from cdlib import algorithms >>> import networkx as nx >>> G = nx.karate_club_graph() >>> coms = algorithms.greedy_modularity(G)
