Web28 mei 2024 · I've recently started practising some graph theory problems, and I wanted to know if there is a method which would allow us to approach the Max Flow problem … The max-flow min-cut theorem is a special case of the strong duality theorem: flow-maximization is the primal LP, and cut-minimization is the dual LP. See Max-flow min-cut theorem#Linear program formulation. Other graph-related theorems can be proved using the strong duality theorem, in particular, Konig's theorem.
Webmax x cTx = min y bTy The strong duality theorem is harder to prove; the proofs usually use the weak duality theorem as a sub-routine. One proof uses the simplex algorithm and relies on the proof that, with the suitable pivot rule, it provides a correct solution.
