WebThe closeness centrality of a vertex is defined as the inverse of the sum of distances to all the other vertices in the graph: 1 ∑ i ≠ v d v i. If there is no (directed) path between vertex v and i, then i is omitted from the calculation. If no other vertices are reachable from v, then its closeness is returned as NaN. cutoff or smaller.

As we look at the \(G_{14}\) graph in Figure 6.1, we see that the colored nodes seem to occupy prominent roles in the connective structure of the graph.If we removed Vertex 9, for example, we would split our graph into three disconnected components.
