2. (15 points) Consider the following integer

2. (15 points) Consider the following integer program: max 8yi - 6y2 s.t. 2y + 2y2 8yi - 6y2 + I + VI VI ALAL VI 11 0 -1 5 integer. 2y2 Y2 yi , Solve this problem by branch-and-bound you may use file bb-final.py to solve LPs). Dis- play your branch and bound tree. In each node, you should write the optimal LP solution found (or say it's infeasible). On each are you should write the new branching condition (eg. yi 7). You should also indicate the sequence in which nodes are explored. If a node is pruned, you must state whether it is pruned due to subproblem) optimality or bound. Finally, you must report the optimal integer solution
