摘要: The problem addressed in this paper is that of orthogonally packing a given set rectangular-shaped items into the minimum number three-dimensional rectangular bins. strongly NP-hard and extremely difficult to solve practice. Lower bounds are discussed, it proved asymptotic worst-case performance ratio continuous lower bound ?. An exact algorithm for filling single bin developed, leading definition an branch-and-bound problem, which also incorporates original approximation algorithms. Extensive computational results, involving instances with up 90 items, presented: It shown many can be solved optimality within reasonable time limit.
