ACA(Ant Colony Algorithm)~([45]) is a sort of heuristic search algorithm. ACA simulate behavior that the ants search route from nest to food. This algorithm has many strongpoints, such as characteristics of positive feedback, distributing and robustness.

• 蚁群算法ACA(Ant Colony Algorithm)来源于对自然界蚂蚁寻找从蚁巢到食物的最短路径并找到回巢路径方法的研究,是一种启发式搜索算法,具有正反馈、较强的鲁棒性,分布式等特点,特别适用于解决组合优化问题。
