：在介绍基本蚁群算法原理的基础上，对其作了许多改进以提高其全局优化寻优速度，并给出了

详尽的新算法编程仿真实现步骤，最后将未改进的基本蚁群算法与本文改进后的蚁群算法分别应用于TSPLIB中的Att532 P问题进行了仿真实验-Abstract：Firstly．the principle of basic ant colony algorithm (ACA)is introduced．Then．a series of schemes

to improve the global optimization properties are proposed，and a detailed programming process is presented．In the

end，an example of Att532TSP is given，which is simulated by using basic ACA and improved ACA．
