介绍了一种求解复杂优化问题的启发式算法--蚁群算法.该方法通过模拟蚁群对"信息素"的控制和利用进行搜索食物的过程-a distributed algorithm for the solution of combinatorial optimization problems which was inspired by the observation of real colonies of ants. We apply ACS to both symmetric and asymmetric traveling salesman problems. Results show that ACS is able to find good solutions to these problems
