Ant colony algorithm is a novel simulated evolutionary algorithm.Preliminary studies have showed that it has many promising futures.Based on the ant colony optimization idea,a new algorithm for continuous optimization problem is presented.The ant's moving direction and step are determined by the best result of last generation.The ant who has found the best way in last cycle will search for a new result in a certain area.The pheromone will be updated after a cycle.Typical examples indicate the better performance of the proposed algorithm.
