2. In the transportation problem in Table 5.27, the total demand exceeds the total supply.
Suppose that the penalty costs per unit of unsatisfied demand are $5, $3, and $2 for
destinations 1,2, and 3, respectively. Use the least-cost starting solution and compute
the iterations leading to the optimum solution.
