Returns the coverage of a partition.
The coverage of a partition is the ratio of the number of intra-community edges to the total number of edges in the graph.
G (NetworkX graph)
partition (sequence) – Partition of the nodes of
G, represented as a sequence of sets of nodes. Each block of the partition represents a community.
The coverage of the partition, as defined above.
- Return type
NetworkXError – If
partitionis not a valid partition of the nodes of
Gis a multigraph, the multiplicity of edges is counted.
