Graph theory closeness

Web1 Answer. Sorted by: 1. According to Wikipedia, a node's farness is defined as the sum of its distances to all other nodes in the graph, and its closeness (or closeness centrality) is the inverse of its farness. If the closeness centrality of a node is 0, then its farness must be infinite, in which case it is either infinitely far from some ...
