WebThe 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. The rest of the nodes (the unreachable ones ...
