Web1 Answer Sorted by: 13 +50 If the capacity of edge c ( e ′) ≥ f ( e ′) + 1 i.e. the max flow remains the same, there is no chance max flow increase, as it would increased without decreasing c ( e ′). Suppose that c ( e ′) = f ( e ′) (this edge is saturated) and we decrease the capacity in 1 unit.

The maximum flow problem can be formulated as the maximization of the electrical current through a network composed of nonlinear resistive elements. In this formulation, the limit of the current  Iin between the input terminals of the electrical network as the input voltage Vin approaches , is equal to the weight of the minimum-weight cut set.
