Web4 Max-Flow / Min-Cut In particular, the previous lemma implies that: max f Value(f) min S Capacity(S;S); where fvaries over ows satisfying c, and Svaries over (s;t)-cuts. The max-ow-min-cut theorem says that these quantities are in fact equal. Theorem 4 (Max-Flow/Min-Cut). Let Gbe a directed graph, and let cbe a capacity function on the edges ... WebAlso, flow problems can be solved with graph theory. In a flow problem, we have one vertex that is the source and one that is the sink. Now we assign capacities to all edges. Each edge can get a flow, which is comparable to a weight, but it cannot exceed the capacities. There are efficient algorithms to calculate the maximum flow from the ...
