global_reaching_centrality(G, weight=None, normalized=True)¶
Returns the global reaching centrality of a directed graph.
The global reaching centrality of a weighted directed graph is the average over all nodes of the difference between the local reaching centrality of the node and the greatest local reaching centrality of any node in the graph . For more information on the local reaching centrality, see
local_reaching_centrality(). Informally, the local reaching centrality is the proportion of the graph that is reachable from the neighbors of the node.
- G (DiGraph) – A networkx DiGraph.
- weight (None or string, optional (default=None)) – Attribute to use for edge weights. If
None, each edge weight is assumed to be one. A higher weight implies a stronger connection between nodes and a shorter path length.
- normalized (bool, optional (default=True)) – Whether to normalize the edge weights by the total sum of edge weights.
h – The global reaching centrality of the graph.
