Floyd-warshall algorithm proof

WebApr 1, 2010 · The Floyd–Warshall algorithm outputs the correct re- sult 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 (see e.g. [8]) and the Floyd–Warshall algorithm will not output the correct re- sult. Rather, it will detect the presence of a ...
