"Weband Fulkerson algorithm runs in time O(nm2) if flows are augmented along shortest paths from source to sink. Independently, Dinic (1970) introduced the con-cept of shortest path networks, called layered net-works, and obtained an O(n2m) algorithm. This bound was improved to O(n3) by Karzanov (1974), who introduced the concept of preflows in a ... " - Dinic cp algorithms

In this post, Goldberg’s “generic” maximum-flow algorithm is discussed that runs in O(V 2 E) time. This time complexity is better than O(E 2 V) which is time complexity of Edmond-Karp algorithm (a BFS based implementation of Ford-Fulkerson). There exist a push …

A. … WebThe following lemma is the key to proving a bound on the running time of Dinic’s algorithm. Lemma 2 The distance to the sink ds strictly increases in each iteration of the algorithm. Clearly this implies that the algorithm takes at most n iterations. Given the two blocking °ow algorithms mentioned above, we get the following results.
