Graph coreness

WebJul 10, 2024 · The closeness centrality of a vertex is defined by the inverse of the average length of the shortest paths to/from all the other vertices in the graph: 1/sum ( d (v,i), i != v) If there is no (directed) path between vertex v and i then the total number of vertices is used in the formula instead of the path length.
