车辆路径问题的改进遗传算法

Improved Genetic Algorithm for Vehicle Routing Problem

通过引入新颖交叉算子 ,构造了一种改进遗传算法 ,此算法摆脱了对群体多样性的要求 ,不存在传统遗传算法常见的“早熟收敛”问题 .将该算法用于解决车辆路径问题 ,实验结果表明 ,此算法可以有效求得车辆路径问题的优化解 ,是求解车辆路径问题的一个较好方案 .

In this paper,a improved genetic algorithm (IGA) is proposed based on the novel crossover operator.IGA avoids effectively the common defects of early convergence and the diversity of population in traditional genetic algorithm .This algorithm can find the optimal or nearly optimal solution to the vehicle routing problem effectively,which is proved by a number of experiments provided by this paper.
