Freeman et al. define the raw or unnormalized flow betweenness of a vertex, v ∈ V (G) as: where f (i, j, G) is the maximum flow from i to j within G (under the assumption of infinite vertex capacities, finite edge capacities, and non-simultaneity of pairwise flows). Intuitively, unnormalized flow betweenness is simply the total ...

WebCurrent-flow Centrality. Typically, geodesic (shortest) paths are considered in the definition of both closeness and betweenness. These are optimal paths with the lowest number of edges or, if the graph is weighted, paths with the smallest sum of edge weights. There are two drawbacks of this approach: WebAbstract. 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 ... dyne incWebMinimum-cost-maximum-flow betweenness centrality, by integrating both land cost and habitat capacity, allows connectivity to be considered within planning processes that seek to maximize species protection at minimum cost.
