If Ford-Fulkerson algorithm terminates, as in Corollary 3.3, then we have a proof (we have a ow f for which jf j= C(S;T), and equality means, as recalled in the proof of Theorem 3.2, that we have both a minimum cut and a maximum ow).

The Ford-Fulkerson algorithm is used to detect maximum flow from start vertex to sink vertex in a given graph. In this graph, every edge has the capacity. Two vertices are provided named Source and Sink. The source vertex has all outward edge, no inward edge, and the sink will have all inward edge no outward edge. greater standard deduction for dependent careWebbound for the Ford-Fulkerson max-flow algorithm.
