遺傳算法(Genetic Algorithm, GA)是近幾年發展起來的一種嶄新的全局優化算法，它借 用了生物遺傳學的觀點，通過自然選擇、遺傳、變異等作用機制，實現各個個體的適應性 的提高。這一點體現了自然界中"物競天擇、適者生存"進化過程。1962年Holland教授首次 提出了GA算法的思想，從而吸引了大批的研究者，迅速推廣到優化、搜索、機器學習等方 面，并奠定了堅實的理論基礎。 用遺傳算法解決問題時，首先要對待解決問題的模型結構 和參數進行編碼，一般用字符串表示，這個過程就將問題符號化、離散化了。也有在連續 空間定義的GA(Genetic Algorithm in Continuous Space, GACS)，暫不討論。

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
