CSE 101 Final Exam Page 1 of 22 1. Knapsack with Branch-and-Bound [16 points] Recall the Knapsack Branch-and-Bound description: 1.Branch: Level = Largest Value, and continue always at that vertex with the largest Upper Bound. 2.Upper Bound: Use the Largest-Relative-Values-Strategy. If this is ≤ the current Best Lower Bound, cross out this vertex; otherwise, proceed.
