遗传算法(Genetic Algorithm, GA)是近几年发展起来的一种崭新的全局优化算法,它借 用了生物遗传学的观点,通过自然选择、遗传、变异等作用机制,实现各个个体的适应性 的提高。这一点体现了自然界中"物竞天择、适者生存"进化过程。1962年Holland教授首次 提出了GA算法的思想,从而吸引了大批的研究者,迅速推广到优化、搜索、机器学习等方 面,并奠定了坚实的理论基础。 用遗传算法解决问题时,首先要对待解决问题的模型结构 和参数进行编码,一般用字符串表示,这个过程就将问题符号化、离散化了。也有在连续 空间定义的GA(Genetic Algorithm in Continuous Space, GACS),暂不讨论。

Routine mampres: To obtain amplitude response from h(exp(jw)). input parameters: h :n dimensioned complex array. the frequency response is stored in h(0) to h(n-1). n :the dimension of h and amp. fs :sampling frequency (Hz). iamp:If iamp=0: The Amplitude Res. amp(k)=abs(h(k)) If iamp=1: The Amplitude Res. amp(k)=20.*alog10(abs(h(k))). output parameters: amp :n dimensioned real array. the amplitude-frequency response is stored in amp(0) to amp(n-1). Note: this program will generate a data file "filename.dat" . in chapter 2

Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution % % compute the forward/backward Campbell/specgtrogram % % INPUT: % y (n x 2) each column is measured from a different sensor % /////// % __ % |s1| y(:,1) % |__| % __ % / \ ________|/ % | | | s2 |/ y(:,2) % \____/ --------|/ % % Fs Sampling frequnecy % % OUTPUT: % B spectrogram/Campbel diagram % x x-axis coordinate vector (time or Speed) % y y-axis coordinate vector (frequency [Hz])

This demo nstrates the use of the reversible jump MCMC simulated annealing for neural networks. This algorithm enables us to maximise the joint posterior distribution of the network parameters and the number of basis function. It performs a global search in the joint space of the parameters and number of parameters, thereby surmounting the problem of local minima. It allows the user to choose among various model selection criteria, including AIC, BIC and MDL
