performance

performance(G, partition)

Returns the performance of a partition.

Deprecated since version 2.6: Use partition_quality instead.

The performance of a partition is the number of intra-community edges plus inter-community non-edges divided by the total number of potential edges.

Parameters

GNetworkX graph

A simple graph (directed or undirected).

partitionsequence

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.
