Distances/shortest paths between all pairs of vertices

WebThe matrix of distances. This matrix has size n 2 and associates to any u v the distance from u to v. The vector of eccentricities. This vector of size n encodes for each vertex v the distance to vertex which is furthest from v in the graph. In particular, the diameter of the graph is the maximum of these values. WebBut I thought maybe the sagemath community would have a natural bias. I was trying to avoid it and find users that had chosen "the other side". $\endgroup$ – Alexandre Martins.
