在文獻中,Sbihi提出一個使用最佳優先分支限界法(branch and bound with best-first solution ),求解多維度多重選擇背包問題(Multidimensional Multiple-Choice Knapsack Problem ,MMKP)的最佳化演算法。本論文主要是使用Sbihi的最佳優先分支限界法,討論如何改進上界(upper bound),提高最佳化演算法的績效,求解多維度多重選擇背包問題。本論文提出EMKP-1演算法與EMKP-2演算法與Sbihi演算法作比較,發現EMKP-1與EMKP-2演算法均能縮短Sbihi演算法的求解時間,且在中小型的問題下,EMKP-1演算法與EMKP-2演算法的執行效率,也比CPLEX高。
Sbihi develops an exact algorithm using branch and bound with best-first solution for solving the Multidimensional Multiple-Choice Knapsack Problem(MMKP). This thesis aims at analyzing and modifying Sbihi’s exact algorithm for MMKP. It tries to improve the upper bound for the branch and bound strategy to solve MMKP. This thesis proposes our two exact algorithm, EMKP-1 algorithm and EMKP-2 algorithm and compare with Sbihi algorithm. The experimental results show that our two algorithms use shorter solving time than Sbihi’s algorithm. Our two algorithm is also better than Cplex with instances of small and medium sizes.
