一、蚁群算法(ACO)概述 蚁群算法(ant colony optimization, ACO)由Marco Dorigo于1992年在他的博士论文中首次提出, 该算法模拟了自然界中蚂蚁的觅食行为。 蚂蚁在寻找食物源时, 会在其经过的路径上释放一种信息素, 并能够感知其它蚂蚁释放的信息素。 信息素浓度的大小表征路径的远近, 信息素浓度越高, 表示对应的...
蚁群优化算法(Ant Colony Optimization Algorithm) 极光喵 蚁群算法(ant colony optimization, ACO) 一, 蚁群算法概述 自然界中有一个神奇的现象,即蚂蚁在没有提示的情况下总是能够找到从巢穴到食物的最短路径,这是为什么呢?原因就是蚂蚁在寻找食物时, 能在其走过的路径上释放一种特殊… 吴小宇 蚁群优化算法 蚁群...
- 判断是否终止：如果迭代次数未达到最大值，则继续迭代；否则，输出最优解并终止计算。3. 算法优化：尽管蚁群算法在解决小规模问题时表现良好，但在大规模问题上可能会遇到收敛速度慢和容易陷入局部最优的问题。为了改进这些问题，可以采用精英蚂蚁系统等策略。4. 算法特点：与传统的路由算法相比，蚁群算法在网络路由...
cult optimization problems [3]. The best performing ACO algorithm for the DVRP is the ACS [13]. There is a multi-colony variation of this algorithm applied to the VRP with time windows [5]. However, in this paper we consider the single colony which has been applied to the DVRP [13]....
