WebThe current-flow betweenness of a vertex v is defined as the amount of current that flows through v in this setup, averaged over all vertex pairs s and t. The current-flow betweenness of a vertex v is the average of the current flow over all source–target pairs: where n (n − 1)/2 is a normalizing constant, and I v(st) is the current flow ... WebIntroduction. Betweenness centrality is a way of detecting the amount of influence a node has over the flow of information in a graph. It is often used to find nodes that serve as a bridge from one part of a graph to another. …
