Max flow linear programming

Web23 jan. 2024 · Then, maximum flow can be written as the primal linear program: max w T f such that f ≤ c, f ≥ 0, A ′ f = 0. Then, the dual linear program corresponds to: min c T d … Web7 nov. 2024 · 1 Answer Sorted by: 0 No. Ford-Fulkerson cannot be used to solve arbitrary linear programming instances. It can only solve instances that are in the form of "max flow in this flow graph". The dual doesn't have that form. The dual is to find the minimum cut.
