0-1 背包问题:给定 n 种物品和一个容量为 C 的背包,物品 i 的重量是w_i,其价值为 v_i。 问:应该如何选择装入背包的物品,使得装入背包中的物品的总价值最大? 为什么叫0-1背包问题呢?显然,面对每个物品,我们只有选择拿取或者不拿两种选择,不能选择装入某物品的一部分,也不能装入同一物品多次。拿就是1,不...

In the case of multi-objective EAs, the outcome is usually an approximation of the Pareto-optimal set, which is denoted as an approximation set, [35,40,41]. The MOMKP combines the two cases of MOKP and the multiple knapsack problem (MKP). Many approximate solution methods have been devel...
and financial management, but more pronounced for theoretical reasons, as Knapsack Problems frequently occur by relaxation of various integer programming problems. In such application, we need to solve a Knapsack Problem each time a bounding function is derived, demanding extremely fast solution ...
