WebNov 10, 2024 · 1 Answer. Sorted by: 1. I'm not sure what you mean by "equivalent", but there may be many different minimum cuts. As an extreme example, if your graph consists of a source s, sink t, and n other vertices each having an edge from s of weight 1 and an edge to t of weight 1, then all of the 2 n possible cuts are minimum cuts of value n. WebMay 26, 2015 · When using Ford-Fulkerson to find max-flow between s and t, the exact choice of flow-graph depends on which paths are found.
