二、TSP问题介绍 旅行商问题(Traveling salesman problem, TSP)是一个经典的组合优化问题,它可以描述为一个商品推销员去若干城市推销商品,要求遍历所有城市后回到出发地,目的是选择一个最短的路线。当城市数目较少时,可以使用穷举法求解。而随着城市数增多,求解空间比较复杂,无法使用穷举法求解,因此需要使用优化算法来解决...

This paper presents a simultaneous pickup and delivery route designing model, which considers the use of express lockers. Unlike the traditional traveling salesman problem (TSP), this model analyzes ...
1). In the process of building the linear orders (see Figs. 2 and 3), we aim to minimize the sum of distances between consecutive points. Therefore, they can also be seen as approximate solutions to the traveling salesman problem (TSP). Fig. 1 Multiple TSP solutions are combined to ...
