WitrynaWe know that computing a maximum flow resp. a minimum cut of a network with capacities is equivalent; cf. the max-flow min-cut theorem. We have (more or less … WitrynaMax flow formulation: assign unit capacity to every edge. Theorem. There are k edge-disjoint paths from s to t if and only if the max flow value is k. Proof. ⇒ Suppose there are k edge-disjoint paths P1, . . . , Pk. Set f(e) = 1 if e participates in some path Pi ; otherwise, set f(e) = 0. Since paths are edge-disjoint, f is a flow of value k.
