networkx.performance

networkx.performance(*args, **kw)[source]

Returns the performance of a partition.

The performance of a partition is the ratio of the number of intra-community edges plus inter-community non-edges 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:

float

The performance of the partition, as defined above.

Raises:

NetworkXError

If partition is not a valid partition of the nodes of G.
