COT 5405, Test 3 SOLUTIONS 1. (10 points) Let T [ i, aa, bb ] be a minimum time needed to complete job i by time aa on machine A and bb on machine bb . Then T [ i, aa, bb ] = a i + min { T [ i - 1 , aa - a i , bb ] , T [ i - 1 , aa, bb - a i ] } , and once we know T [ n, Σ a i , Σ a i ] the problem is solved. Overall time complexity is O ( M 2 N ). 2. (10 points) Let P [ i ] be optimal sequence of trades obtained using i

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
