Shortest path floyd warshall algorithm
SpletThe Floyd–Warshall algorithm computes the weight of the shortest walk between any two vertices (a walk is defined like a path, but with repeated vertices allowed). Assuming all weights are positive, the shortest walk is always a path, since if a walk hits the same vertex twice, then we can remove the cycle to obtain a shorter walk.
