本文尝试用强化学习(Reinforcement Learning)来求解 TSP (Traveling Salesman Problem)。更确切地说,我们将采用Q-learning来求解 TSP 。TSP 就是给定N个城市/点,找到一条最短路径,把所有城市都走一遍,并且要求能回到起点。求解结果如下图所示:随机给定一些城市的坐标,算法经过多轮迭代后,能给出一条最短路径。 求解...
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...

The edge blockages are real-time, meaning that the salesman knows about a blocked edge whenever it occurs. We first show a lower bound on the competitive ratio and present an online optimal algorithm for the problem. While this optimal algorithm has non-polynomial running time, we present ...

A Python implementation of Tabu Search Algorithm for the Traveling Salesman Problem - iamjunyeong/TS-for-TSP
In this TSP variant, the salesman travels through all cities but does not return to the city where they started. The construction of a single TSP path, illustrated in Fig. 2 and Algorithm 2, starts by selecting two random points from the data (lines 3–4). The dataset is then split ...
