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 … WebThe max flow is 5. However, there is no cut whose capacity is 5. This is because the infinite edge capacities force all a, b, c, d, e to belong to the same set of a cut (otherwise there would be an ∞ weight in the cut-set). network-flow Share Cite Follow edited Sep 30, 2013 at 5:40 asked Sep 30, 2013 at 5:29 Janathan 3 3 Add a comment 1 Answer WebThe Max-Flow Min-Cut Theorem Math 482, Lecture 24 Misha Lavrov April 1, 2024.
