WebCorollary 3.4.(Max Flow/Min Cut) The minimum cut value in a network is the same as the maximum ow value. Proof. 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). WebFlows in Networks. In this classic book, first published in 1962, L. R. Ford, Jr., and D. R. Fulkerson set the foundation for the study of network flow problems.
