## Group Betweenness Centrality## Definition
Group betweenness centrality (GBC) shows the proportion of geodesics connecting pairs of non-group members that pass through a group of nodes.
GBC of a group of nodes stands for the fraction of shortest paths between pairs of nodes in a network that passes through at least one of the nodes in the group. Thus, GBC can be used for estimating the ability of a group of collaborating nodes to monitor the network traffic. [EVERETT, M. G. 1999, PUZIS, R., 2009] Defined the group betweenness of u and v as: ## B(u, v) = C |
