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 WebMar 9, 2024 · As far as I know, SAS has the only commercial solver with an automated implementation of Dantzig-Wolfe decomposition. You can use automatic block-detection routines or specify the block structure yourself. From there, everything is automated, including parallelization of the subproblem solves.
