WebbIn dual simplex method, the LP starts with an optimum (or better) objective function value which is infeasible. Iterations are designed to move toward feasibility without violating optimality. At the iteration when feasibility is restored, the algorithm ends. In order to maintain optimality and move toward feasibility at each iteration, the flip the tube four christmas
