8. TORA Experiment. Consider the Diet Model and let the objective function be given as Minimize z = .8x1 + .8X2 Use TORA to show that the optimum solution is associated with two distinct corner points and that both points yield the same objective value. In this case, the problem is said to have alternative optima. Explain the conditions leading to this situation and show that, in effect, the problem has an infinite number of alternative optima, then provide a formula for determining all such solutions.
