Ford fulkerson algorithm min cut

WebApr 27, 2016 · The minimum cut is a partition of the nodes into two groups. Once you find the max flow, the minimum cut can be found by creating the residual graph, and when traversing this residual network from the source to all reachable nodes, these nodes define one part of the partition. Call this partition A. WebMin-Cut Max-Flow theorem allows us to use the answer from one as the answer to the other. Can use Ford-Fulkerson Algorithm for s-t problem, and Krugals for global …
