模拟退火算法——组合优化
模拟退火算法主要用于解决组和优化问题，它是模拟物理中晶体物质的退火过程而开发的一种优化算法。在对固体物质进行模拟退火处理时，通常先将它加温熔化，使其中的粒子可自由运动，然后随着温度的逐渐下降，粒子也逐渐形成了低能态的晶格。若在凝结点附近的温度下降速率足够慢，则固体物质一定会形成最低能态的基态。
对于组合优化问题来说，它也有这样的类似过程。组合优化问题解空间中的每一点都代表一个具有不同目标函数值的解。所谓优化，就是在解空间中寻找目标函数最小（大）解的过程。若把目标函数看成能量函数，某一控制参数视为温度 T，解空间当作形态空间，那么寻找基态的过程也就是求目标函数极小值的优化过程。
(Simulated annealing algorithm- combinatorial optimization
Simulated annealing algorithm used to solve optimization problems and the group, it is the physical simulation of the crystal material in the annealing process and the development of an optimization algorithm. Solid substances in the simulated annealing process, it is usually heated it first melts, so that the particles are free to exercise, then gradually decreased as the temperature of the particles gradually formed a lower state of the lattice. If the temperature drops near the condensation rate slow enough, the solids will form the lowest energy state of the ground state.
For combinatorial optimization problems, it also has such a similar process. Combinatorial optimization problem the solution space of each point represents a different objective function value of the solution. The so-called optimization, is in the solution space to find the minimum objective function (large) solution process. If the objective function a)

Fisher-linear-discriminant-method
此为模式识别中的Fisher线性判别方法求分类器。进行了男、女错误率和总错误率的统计。
全部程序流程如下：
1、读取FAMALE.TXT文件把身高或体重给数组，并求x1的样本均值m1和内离散度S1；
2、读取MALE.TXT文件把身高或体重给数组，并求x2的样本均值m2和内离散度S2；
3、求最佳变换向量和阀值点；
4、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M；
5、把最佳变换向量和阀值点、x代入判别方程g（x）；
6、对本判别的错误率进行统计。(This is the pattern recognition method, to calculate the Fisher linear discriminant classifier .Were male , female and total error rate error rate statistics .
All program flow is as follows :
1 , read FAMALE.TXT file to height or weight to the array, and find the sample mean m1 x1 and internal dispersion S1
2 , read MALE.TXT file to height or weight to the array, and find the sample mean m2 and x2 within the dispersion S2
3 , for the best transformation vector and the threshold point
4 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M
5 , the best transformation vector and the threshold point , x substituted into the discriminant equation g (x)
6 , determine the error rate of the statistics .
