LIBSVM 是台湾大学林智仁 (Chih-Jen Lin) 博士等开发设计的一个操作简单、易于使用、快速有效的通用 SVM 软件包，可以解决分类问题（包括 C- SVC 、n - SVC ）、回归问题（包括 e - SVR 、 n - SVR ）以及分布估计（ one-class-SVM ）等问题，提供了线性、多项式、径向基和 S 形函数四种常用的核函数供选择，可以有效地解决多类问题、交叉验证选择参数、对不平衡样本加权、多类问题的概率估计等。(LIBSVM is林智仁Taiwan University (Chih-Jen Lin) Dr. develop design a simple, easy to use, fast and effective generic SVM software package, can solve the classification problems (including the C-SVC, n- SVC), regression ( including e- SVR, n- SVR) as well as the distribution of estimates (one-class-SVM) and so on, provides a linear, polynomial, radial basis function and the S-shaped kernel function of four commonly used for selection, can effectively to solve a wide range of issues, cross-validation to choose the parameters of the imbalance in the weighted sample, multi-category probability estimation.)

梯度下降法是最早最简单，也是最为常用的最优化方法。梯度下降法实现简单，当目标函数是凸函数时，梯度下降法的解是全局解。一般情况下，其解不保证是全局最优解，梯度下降法的速度也未必是最快的。梯度下降法的优化思想是用当前位置负梯度方向作为搜索方向，因为该方向为当前位置的最快下降方向，所以也被称为是”最速下降法“。最速下降法越接近目标值，步长越小，前进越慢。(The gradient descent method is the earliest and most simple and most commonly used optimization method. The gradient descent method is simple to realize. When the objective function is a convex function, the solution of the gradient descent method is a global solution. In general, the solution is not guaranteed to be the global optimal solution, and the gradient descent method is not necessarily the fastest. The optimization idea of gradient descent method is to use the current position negative gradient direction as the search direction, because the direction is the fastest descending direction of the current position, so it is also called the steepest descent method. The faster the slowest descent approach is closer to the target, the smaller the step, the slower the progress.)

设雷达信号是码宽为0.5微妙，中心频率是10MHz的7为巴克码2PSK信号，接收的雷达回波中频采样频率为为40MHz，中频进行正交下变频。假设在13.5km处有一个点目标，仿真该雷达的脉冲压缩处理。 已通过测试。 (Let the radar signal is yards wide 0.5-subtle, the center frequency of the the Buck the code 2PSK signal, the received radar echo IF sampling frequency of 10MHz to 40MHz, IF quadrature down-conversion. Assuming the 13.5km at a point target simulation of the radar pulse compression processing. Has been tested.)

常胜将军 :在计算机后走的情况下，要想使计算机成为“常胜将军”，必须找出取 关键。根据本题的要求枷以总结出，后走一方取子的数量与对方刚才一步取子的数量之和等于，就可以保证最后一个子是留给先取子的那个人的。(Ever Victorious General: On the computer where to go, in order to make the computer become " Ever Victorious generals" must be taken to find the key. According to the requirements of this title thoughts to conclude that one party to take the child away after the number of step with each other just to take the child and is equal to the quantity, we can ensure that a child is left to the first final to take the child of that individual.)
