Dantzig–wolfe decomposition method
http://www2.imm.dtu.dk/courses/02717/dantzig-wolfe3/dantzigwolfe.pdf 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).
