Suppose that a constraint that should be in a maximization linear program is left out of the formulation by mistake. Let P denote the correct formulation and let Q denote the incorrect formulation. Which of the following could happen? P has an optimal solution, but Q is an infeasible linear program. Q has a smaller feasible region than P. the optimal value for Q is lower than the optimal value for P. P has a unique optimal solution while Q is unbounded
