旅行商问题
基于遗传算法求解旅行商问题(TSP)
首先采用随机生成点函数,生成一幅地图。假定一个点对应一个城市。
之后用该地图求解旅行商问题(Solving Traveling Salesman Problem (TSP) Based on Genetic Algorithms
Firstly, a map is generated by random generating point function. Suppose a point corresponds to a city.
Then the map is used to solve the traveling salesman problem.)
