Question:
Investigate the optimality of the Reddy Mikks solution (Example 4.3-1) for each of the following objective functions. If the solution changes, use post-optimal analysis to determine the new optimum. (The optimal tableau of the model is given in Example 3.3-1.)
(a) Z = 3x1 + 2x2
(b) Z = 8x1 + 10x2
(c) Z = 2x1 + 5x2
