current_flow_closeness_centrality
(G, weight='weight', dtype=<type 'float'>, solver='lu')[source]¶ Compute currentflow closeness centrality for nodes.
Currentflow closeness centrality is 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
 dtype (data type (float)) – Default data type for internal matrices. Set to np.float32 for lower memory consumption.
 solver (string (default=’lu’)) – Type of linear solver to use for computing the flow matrix. Options are “full” (uses most memory), “lu” (recommended), and “cg” (uses least memory).
Returns: nodes – Dictionary of nodes with current flow closeness centrality as the value.
Return type: dictionary
