摘要
根据蚁群算法与模拟退火算法的特性,提出了求解旅行商问题的混合算法。由模拟退火算法生成信息素分布,然后由蚁群算法根据累计更新的信息素找出若干组解,再经过模拟退火算法在邻域内找另外一个解的操作,得到更有效的解。与模拟退火算法、标准遗传算法、蚁群算法和随机初始化的蚁群算法进行比较,4种混合算法效果都比较好,策略D的混合算法效果最好。
By use of the properties of ant colony algorithm and simulated annealing algorithm,a hybrid algorithm is proposed to solve the traveling salesman problems.First,it adopts simulated annealing algorithm to give information pheromone to distribute.Second,it makes use of the ant colony algorithm to get several solutions through information pheromone accumulation and renewal.Finally,by searching a solution of neighborhood of simulated annealing algorithm,the effective solutions are obtained.Comparing with the simulated annealing algorithm,the standard genetic algorithm,the standard ant colony algorithm,and statistics initial ant colony algorithm,all the 4 hybrid algorithms are proved effective.Especially the hybrid algorithm with strategy D is a simple and effective better algorithm than others.
