Dantzig–wolfe decomposition method

WebApr 13, 2024 · Then, the Dantzig–Wolfe decomposition is utilized to solve the planning model, where the master problems and subproblems are one-to-one. Each possesses a moderate scale of decision variables, which makes it conducive to improve the computational performances. (iii) WebHow can we apply the revised simplex method to (MP)? We need an initial basic feasible solution and a way to generate new columns as needed. For the initial solution, we can solve, say: mincT j xj;xj 2 Qj; for each j. If infeasible, quit; otherwise we generate a vertex, say vj1 (either optimal or adjacent to an unbounded ray).
