New Genetic Algorithm for Vehicle Routing Problem with Time Window
【摘要】 提出一种改进的遗传算法 ,用于求解带时间窗的车辆路由问题 .在算法中采用了直观的自然数编码机制、三复本锦标赛的选择方法和改进的启发式交叉算子 ,实验表明该方法用于求解带时间窗的车辆路由问题的有效性 .
【Abstract】 Presented an improved genetic algorithm for vehicle routing problem with time window(VRPTW). The intuitive integer string representation, a new selection method with tournament of three copies, and an improved heuristic crosser were applied. The experimental results showed its validity for vehicle routing problem with time Window(VRPTW).
