Every undirected graph can be represented as directed graph by replacing every edge ( i, j) with 2 edges ( i, j); ( j, i). And if you're running Floyd–Warshall algorithm on such directed graph - it would work correctly, as always. It does not work correctly if the undirected graph has a negative edge.
