Dantzig-wolfe decomposition algorithm

Web4.2 Dantzig andWolfeDecomposition. Dantzig and Wolfe decomposition is an algorithm that was designed originally to solve large LP with special structures [Dan60]. The basic idea of this technique is to apply the Minkowsky Theorem or the Representation Theorem for convex polyhedra (see Theorem 4.1) to a subset of constraints of WebDantzig–Wolfe decomposition method, see Section 6.1.1). We finally note that convergence of this scheme in its full generality does not immediately follow from Theorem 1, although it does for some special cases, such as Dantzig–Wolfe decomposition. The exploitation of the generic column generation principle might lead to new, and hopefully ...
