In this lecture, we prove optimality of the Ford-Fulkerson theorem, which is an immediate corollary of a. Theorem. Max-flow min-cut theorem. 1. This theorem states that the maximum flow through any network from a given source to a given sink is exactly the sum of the edge weights that, if removed, would totally disconnect the source from the sink.
