The optimization behavior of the self-adaptation (SA) evolution strategy (ES) with intermediate multirecombination (the (=I )-SA-ES) using isotropic mutations is investigated on the general elliptic objective function. An asymptotically exact quadratic progress rate formula is derived. This is used to model the dynamical ES system by a set of difference equations. The solutions of this system are used to analytically calculate the optimal learning parameter  . The theoretical results are compared and validated by comparison with real (=I )-SA-ES runs on typical elliptic test model cases. The theoretical results clearly indicate that using a model-independent learning parameter  leads to suboptimal performance of the (=I )-SA-ES on objective functions with changing local condition numbers as often encountered in practical problems with complex fitness landscapes.

matalb编写的语音编码的有关程序，有兴趣的可以下载(matalb prepared speech coding procedures are interested can download)

说明：  kpca的matlab源码，只要有人脸库就可用！(kpca of matlab source, as long as people face database can be used!)

信噪比=20，迭代步长=0.035，本次程序设计还是验证了RLS比LMS收敛快的效果。(SNR = 20, iteration step = 0.035, this program is designed to verify the RLS faster than the LMS convergence effect.)

正确读取雷达基数据，适合初学者使用，是个不错的例子。(Read correctly radar base data, suitable for beginners to use, is a good example.)
