This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.

利用GA來模擬鳥群尋找食物的行為，方法就是找尋距離食物最近的鳥之周圍區域及根據自己本身飛行的經驗判斷食物的所在(The use of GA to simulate the behavior of the flock in search of food, the methodology is to find the nearest bird food from around the region and according to their own experience of flying to judge the location of food)
