Web7 de abr. de 2014 · 22. 22 Max-Flow Min-Cut Theorem Augmenting path theorem (Ford-Fulkerson, 1956): A flow f is a max flow if and only if there are no augmenting paths. MAX-FLOW MIN-CUT THEOREM (Ford-Fulkerson, 1956): the value of the max flow is equal to the value of the min cut. We prove both simultaneously by showing the TFAE: (i) f is a … Web13 de set. de 2024 · Such a network is called a flow network, if we additionally label two vertices, one as source and one as sink. ... Therefore, the maximum flow is bounded by the minimum cut capacity. The max-flow min-cut theorem goes even further. It says that the capacity of the maximum flow has to be equal to the capacity of the minimum cut.
