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. Witryna10 kwi 2024 · The Edmonds-Karp Algorithm is a specific implementation of the Ford-Fulkerson algorithm. Like Ford-Fulkerson, Edmonds-Karp is also an algorithm that deals with the max-flow min-cut problem. Ford-Fulkerson is sometimes called a method because some parts of its protocol are left unspecified. Edmonds-Karp, on the other …
