We give the proof of the correctness and termination of the algorithm, including a full analysis of its running time complexity with respect to the times to compute the ⊕ and ⊗operations. We also give a generic algorithm for solving single-source shortest-distance problems in weighted directed acyclic graphs.

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.
