16. After solving a transportation problem with positive shipping costs cij along all arcs, we increase the supply at one source and the requirement at one destination in a manner that will maintain equality of total supply and total demand. Solving the Minimum-Cost Flow Problem 265 a) Would you expect the shipping cost in the modified problem with a larger total shipment of goods to be higher than the optimal shipping plan from the original problem? b) Solve the following transportation problem: c) Increase the supply at source S1 by 1 unit and the demand at demand center D3 by 1 unit, and re-solve the problem. Has the cost of the optimal shipping plan decreased? Explain this behavior
