蚁群算法解决TSP问题。通过蚁群算法解决一个城市的结合以及城市之间的旅行代价，寻找经过每个城市一次且仅一次而最终返回的旅行最小代价，及寻找最短路径。-Ant colony algorithm to solve TSP problem. Through the combination of ant colony algorithm to solve a city and cost of travel between cities, seeking after each city once and only once and eventually return to the minimum cost of travel, and to find the shortest path.
