networkx.algorithms.community.quality.performance¶

performance
(G, partition)[source]¶ Returns the performance of a partition.
The performance of a partition is the ratio of the number of intracommunity edges plus intercommunity nonedges with the total number of potential edges.
Parameters:  G (NetworkX graph) – A simple graph (directed or undirected).
 partition (sequence) – Partition of the nodes of
G
, represented as a sequence of sets of nodes. Each block of the partition represents a community.
Returns: The performance of the partition, as defined above.
Return type: Raises: NetworkXError
– Ifpartition
is not a valid partition of the nodes ofG
