global_efficiency

global_efficiency(G)

Returns the average global efficiency of the graph.

The efficiency of a pair of nodes in a graph is the multiplicative inverse of the shortest path distance between the nodes. The average global efficiency of a graph is the average efficiency of all pairs of nodes [1].

Parameters:

Gnetworkx.Graph

An undirected graph for which to compute the average global efficiency.

Returns:

float

The average global efficiency of the graph.

Notes

Edge weights are ignored when computing the shortest path distances.
