Chapter 8, Problem 8.3.3(choose chapter or problem)
Suppose A is the identity matrix (so that m = n), and the vectors b and c are nonnegative. Explain why x = b is optimal in the minimum problem, find y in the maximum problem, and verify that the two values are the same. If the first component of b is negative, what are x and y ?
