Firstly, the … WebJan 26, 2024 · During one of my course's homework I have found myself trying to come up with a different proof of correctness for the Floyd-Warshall algorithm. However, the feedback was not great although no detailed explanation was given. Could you help me spot mistakes in my proof?
Webgeneric algorithm. 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. WebIntuition behind Floyd-Warshall being faster.
