Problem 2. (20 marks) Consider the following integer linear programming problem:
max T^2 s.t. 2T1 + 2T2 < 121 + 212 < 7 T1, T2 > 0 and are integers.
Use binary representation of the variables to reformulate this integer LP problem into a binary integer LP problem. (Note: You can work on the constraints to reduce the range of your choices. For example, (21, 12) (1,2) is not a feasible solution; You can draw a figure to help you if you want.)
(b) Use the binary integer branch-and-bound algorithm to solve the problem developed above.
Write down the optimal solution and the optimal value for the original integer LP problem.
