networkx.algorithms.centrality.current_flow_closeness_centrality(G, normalized=True)

Compute current-flow closeness centrality for nodes.

A variant of closeness centrality based on effective resistance between nodes in a network. This metric is also known as information centrality.

Parameters :

G : graph

A networkx graph

normalized : bool, optional

If True the values are normalized by 1/(n-1) where n is the number of nodes in G.

Returns :

nodes : dictionary

Dictionary of nodes with current flow closeness centrality as the value.

Notes

The algorithm is from Brandes [R90].

See also [R91] for the original definition of information centrality.
