(c) Find the alternate optimal solution. (d) Solve this problem graphically as well, and illus- trate the alternate optimal corner points. : M7-26 At the third iteration of a particular LP maximization problem, the tableau at the bottom of this page is es- tablished. What special condition exists as you im- prove the profit and move to the next iteration? Proceed to solve the problem for the optimal solution.
