networkx.algorithms.centrality.out_degree_centrality

out_degree_centrality(G)[source]

Compute the out-degree centrality for nodes.

The out-degree centrality for a node v is the fraction of nodes its outgoing edges are connected to.

Parameters

G (graph) – A NetworkX graph

Returns

nodes – Dictionary of nodes with out-degree centrality as values.

Return type

dictionary

Raises

NetworkXNotImplemented – If G is undirected.

Notes

The degree centrality values are normalized by dividing by the maximum possible degree in a simple graph n-1 where n is the number of nodes in G.

For multigraphs or graphs with self loops the maximum degree might be higher than n-1 and values of degree centrality greater than 1 are possible.
