Resistance distance : ウィキペディア英語版 | Resistance distance In graph theory, the resistance distance between two vertices of a simple connected graph, ''G'', is equal to the resistance between two equivalent points on an electrical network, constructed so as to correspond to ''G'', with each edge being replaced by a 1 ohm resistance. It is a metric on graphs. ==Definition==
On a graph ''G'', the resistance distance Ω''i'',''j'' between two vertices ''vi'' and ''vj'' is : where Γ is the Moore–Penrose inverse of the Laplacian matrix of ''G''.
