WebThe Ford-Fulkerson algorithm is an algorithm that tackles the max-flow min-cut problem. That is, given a network with vertices and edges between those vertices ... What is the … WebThe running time for the Ford-Fulkerson algorithm is O(m0F) where m0is the number of edges in E0and F = P e2 (s) (c e). In case of bipartite matching problem, F jVjsince there can be only jVjpossible edges coming out from source node. So the total running time is O(m0n) = O((m+ n)n).

WebFord-Fulkerson algorithm is a greedy approach for calculating the maximum possible flow in a network or a graph. A term, flow network, is used to describe a network of vertices and edges with a source (S) and a sink (T). Each vertex, except S and T, can receive and send an equal amount of stuff through it.
