| 摘 要： | 和声搜索算法是一种启发式优化算法,针对现有改进的和声搜索算法(IHS)的不足,提出了一种改进的自适应和声搜索算法(IAHS).在该算法中,采用自适应的和声保留概率、音调调节概率和音调调节步长产生新解,每次迭代产生多个新解,充分利用和声记忆库的信息.本文用了5个标准的测试函数对该算法进行测试,结果表明该算法(IAHS)有较强的寻优能力和跳出局部最优解的能力.

| Abstract: | Harmony Search(HS) is a heuristic optimization method.Based on the purpose of avoiding the disadvantage of improved harmony search(IHS) algorithm,a new adaptive harmony search algorithm is presented.Adaptive harmony memory consideration rate,pitch adjusting rate and band width are used to produce new solutions.In each iteration,several solutions are generated.It makes full use of information of harmony memory.Finally,the proposed algorithm is tested by five benchmark function and contrasted with HIS,AHSPSO.The test results show the favorable abilities of accuracy and escaping local minimums. |
