Description:
There appear to be two versions of the Dual Bin Packing problem in the literature. In addition, one of the versions has a counterpart in the cutting stock literature, known as the Skiving Stock Problem. This paper outlines branch-and-price algorithms for both. We introduce combinatorial upper bounds and well-performing heuristics from the literature in the branch-and-price framework. Extensive computational tests indicate that the branch-and-price approach is superior to the existing branch-and-bound procedures, based on combinatorial bounds. The tests illustrate the influence of different problem characteristics on the computation time and the limits of the branch-and-price approach.
