摘　　要：针对实值函数优化问题,基于基本和声搜索算法及蝙蝠算法,提出一种新的改进和声搜索算法HS-Bat.新算法保留了和声搜索的搜索机理,但对和声搜索中和声记忆库外的搜索方法用蝙蝠算法作了改进,对和声记忆库内新解产生方法也作了相应的调整,从而提高了原算法的搜索效率.利用Matlab编程对改进后算法寻找最优解的稳定性及精确度进行测试.结果表明改进后的算法有更好的效果,值得进一步研究与推广应用.Aiming at the real function optimization problem ,a new algorithm based on HAS （harmony search algo-rithm） and BA（bat-algorithm） were put forward which was called HS-Bat algorithm .The new algorithm re-tained the harmony search algorithm ,by using bat algorithm ,the search method of outside the harmony memory is improved ,new solution method of the harmony memory was adjusted accordingly so as to improve the search-ing efficiency of the original algorithm .By using the software of Matlab the stability and precise in optimum so-lutions were test .The results show that HS-Bat algorithm is better than HS and BA .It is worthy of further study .
