带分组项的双目标多背包问题

Bi-Criteria Multiple Knapsack Problem with Grouped Items

Francisco Castillo-Zunino, Pinar Keskinocak

摘要:

物品分组的多背包问题的目标是通过在多个背包之间分配物品组来最大化报酬,同时考虑背包的容量。要么分配组中的所有项目,要么不分配任何项目。我们提出了保证奖励不低于最优解的算法,并对超出的背包容量进行了限制。为了获得容量可行的解决方案,我们提出了一个二进制搜索启发式结合这些算法。我们在随机生成的实例上进行了大量的实验,测试了算法和算法的性能,并表明它们是高效和有效的,即,它们运行得相当快,并产生高质量的解决方案。

英文摘要:

The multiple knapsack problem with grouped items aims to maximize rewards by assigning groups of items among multiple knapsacks, considering knapsack capacities. Either all items in a group are assigned or none at all. We propose algorithms which guarantee that rewards are not less than the optimal solution, with a bound on exceeded knapsack capacities. To obtain capacity-feasible solutions, we propose a binary-search heuristic combined with these algorithms. We test the performance of the algorithms and heuristics in an extensive set of experiments on randomly generated instances and show they are efficient and effective, i.e., they run reasonably fast and generate good quality solutions.
