布谷鸟搜索算法Cuckoo Search（CS）,也叫杜鹃搜索,是由剑桥大学Xin-She Yang(杨新社)教授和S.Deb于2009年提出的一种新兴启发算法CS算法通过模拟某些种属布谷鸟(Cuckoo Species)的寄生育雏(Brood Parasitism)来有效地求解最优化问题的算法.同时，CS也采用相关的Levy飞行搜索机制。(The cuckoo search algorithm Cuckoo Search (CS), also called the azalea search,

有理分式多项式法也称幂多项式法和Levy法，用于进行模态参数识别的数学模型采用频响函数的有理分式形式。

将利用的柯西和莱维改进的GBO算法应用到DNA序列的筛选中，可以提高DNA编码集合的下界。(Applying the modified GBO algorithm by Cauchy and Levy to the screening of DNA sequences, the lower bound of DNA coding set can be increased)

利用柯西、高斯、莱维三种突变策略改进GBO算法，通过测试结果表明，改进的算法有了显著性的提高。(Three mutation strategies of Cauchy, Gauss and Levy are used to improve the GBO algorithm, and the test results show that the improved algorithm has a significant improvement.)
