摘要:0-1背包问题是一个典型的组合优化问题,在计算理论中属于NP完全问题.它是在资源有限的条件下,追求总的最大收益的资源有效分配问题.遗传算法法是求解组合优化问题的一种方法,但用简单遗传算法解决不可行性和背包承重利用不足的可行解问题时效果并不理想,所以将遗传算法与其他算法结合进行该进求解.混合遗传算法大大提高了算法搜索效率,在求解问题上具有更好的稳定性、收敛性、计算效率,成为解决0-1背包问题的有效算法.38908 毕业论文关键词:组合优化问题;混合遗传算法;约束条件处理;最优解
Based on Hybrid Genetic Algorithm to Solve 0-1
Knapsack Problem
Abstract:0-1 knapsack problem is a typical combinatorial optimization problem, in the computational theory belongs to NP-complete problems. It is under the condition of limited resources, the pursuit of total maximum gain effective resource allocation problem. Genetic algorithm method is a method for solving combinatorial optimization problem, the feasibility and backpack bearing with simple genetic algorithm to solve not feasible solution with insufficient when the effect is not ideal so combines genetic algorithm and other algorithms to the into the solution. Hybrid genetic algorithm greatly improve the efficiency of the algorithm search, on solving problems has better stability, convergence and computational efficiency, become the effective algorithm to solve 0-1 knapsack problems.
