Table 1 Definitions for the centrality measures. Let G = (V, E) be an undirected or directed, (strong) connected graph with n = |V| vertices; deg(v) denotes the degree of the vertex v in an undirected graph; dist(v, w) denotes the length of a shortest path between the vertices s and t; σ st denotes the number of shortest paths from s to t and σ st (v) the number of shortest path from s to t that use the vertex v. Let A be the adjacency matrix of the graph G. For a more detailed description and further references please see [8, 27]. Abbreviations used: S.-P.: shortest path, C.-F.: current flow.
