WebMar 1, 2013 · Simulated flow is a common method adopted by many centrality metrics, such as flow betweenness centrality, which assumes that the information spreads freely in the entire network. WebMay 24, 2016 · Flow Betweenness. Freeman proposes Flow Betweenness, denoted by C F, to develop measures of centrality into weighted and directed network analysis. It is based on Fulkerson’s min-cut, max-flow theorem, which means the maximum flow from node i to j is exactly equal to the minimum cut capacity, that is, the smallest capacity of any of the i …

We consider variations of two well-known centrality measures, betweenness and closeness, with a different model of information spread. Rather than along shortest paths only, it is assumed that information spreads efficiently like an electrical current. We prove that the current-flow variant of closeness centrality is identical with ...
