Let’s now do the same for betweenness centrality, which is defined as the number of geodesic paths (shortest paths) that go through a given node.Nodes with high betweenness might be influential in a network if, for example, they capture the most amount of information flowing through the network because the information tends to flow through … butterfly shorts girls https://jd-equipment.com
