2、案。随着蚁群算法研究的兴起，人们发现采用蚁群模型进行聚类能够更加有力的解决现实问题。本文主要先研究了业界一些蚁群算法和聚类算法，充分深入了解了有关聚类蚁群算法的基本原理和特性。而通过研究发现人工蚁群算法本质上是一个并行系统，因此，研究并行蚁群算法对于提高运算速度具有重要的意义，在归纳总结的基础上，本文了将并行算法和聚类蚁群算法相结合，提出了一种新的聚类蚁群优化算法，同时将改良后的优化算法针对传统的TSP 问题、二次分配问题进行了对比，实验结果表明该算法不仅是有效的，而且其性能更加的优越。本文提出了并行性和聚类蚁群相结合的方法，给出了一种并行蚁群算法，该算法使用并行搜索，并且采用根据目标函数值自
