中文说明：基于遗传算法，有从同一起点出发遍历各城市的程序，也有从不同起点出发遍历所有城市的城市，可更改旅行商数量，城市坐标等，可移植性特别强
English Description：
Based on genetic algorithm, there are programs to traverse all cities from the same starting point, and there are also programs to traverse all cities from different starting points. The number of travel agents and city coordinates can be changed, and the portability is particularly strong
