摘要
We develop a branch-and-bound algorithm to solve a nonlinear class of 0-1 knapsack problems. The objective function is a product of m greater than or equal to 2 affine functions, whose variables are mutually exclusive. The branching procedure in the proposed algorithm is the usual one, but the bounding procedure exploits the special structure of the problem and is implemented through two stages: the first stage is based on linear programming relaxation; the second stage is based on Lagrangian relaxation. Computational results indicate that the algorithm is promising.
