WebExpert Answer. 9-12 Return to the graph of Exercise 9-5, and suppose that we seek shortest paths from all nodes to all other nodes. (a) Explain why Floyd-Warshall Algorithm 9 B can be employed to compute the required shortest paths. (b) Apply Algorithm 9B to compute the length of shortest paths from all nodes to all other nodes. WebMar 30, 2013 · The Floyd-Warshall algorithm outputs the correct result as long as no negative cycles exist in the input graph. In case that a negative cycle exists, computing a shortest (simple) path is an NP-hard problem and the Floyd-Warshall algorithm will not output the correct result.
