load_centrality¶

load_centrality
(G, v=None, cutoff=None, normalized=True, weight=None)¶ Compute load centrality for nodes.
The load centrality of a node is the fraction of all shortest paths that pass through that node.
Parameters:  G (graph) – A networkx graph
 normalized (bool, optional) – If True the betweenness values are normalized by b=b/(n1)(n2) where n is the number of nodes in G.
 weight (None or string, optional) – If None, edge weights are ignored. Otherwise holds the name of the edge attribute used as weight.
 cutoff (bool, optional) – If specified, only consider paths of length <= cutoff.
Returns: nodes – Dictionary of nodes with centrality as the value.
Return type: dictionary

Notes
Load centrality is slightly different than betweenness. It was originally introduced by [2]. For this load algorithm see [1].
