WebThe key insight in the algorithm is that, for any integers i ≥ μ and k ≥ 0, x i = x i + k λ, where λ is the length of the loop to be found and μ is the index of the first element of the cycle. But it is followed by the following point which I could not understand. in particular, i = k λ ≥ μ, if and only if x i = x 2 i. 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 ...
