Abstract:
This paper proposes a rigorous algorithm for solving the 0-1 polynomial knapsack problem. The algorithm uses a branch-and-bound method based on Lagrangian relaxation and dual search. The upper bounds are computed with the outer approximation method where Lagrangian relaxations are solved with the maximumflow algorithm. Heuristic procedures are derived to search for feasible solutions, and some variables in the optimal solution are determined before the branch-and-bound process, thus improving performance of the algorithm. Promising computational results are reported for test problems.
Key words: branch-and-bound method, Lagrangian relaxation, maximum-flow algorithm
