WebA graph geodesic is the shortest path between two vertices of a graph. The graph diameter is the longest possible length of all graph geodesics of the graph. PseudoDiameter finds an approximate graph diameter. It works by starting from a vertex u, and finds a vertex v that is farthest away from u. WebSince G has diameter exactly 2, w is adjacent to some neighbor of v. Let s = deg ( w). Because G has diameter 2, each of the n − 2 − s neighbors of v that are not neighbors of w must be adjacent to some neighbor of w. Hence, there are a total of at least. ( n − 2) + s + ( n − 2 − s) = 2 n − 4. edges in G. canon mx925 scanner treiber windows 10
