一个贪吃蛇AI的js实现，基本思想：先模拟一条蛇使用去吃食，若吃到食物后（广度优先寻最短路径）蛇处于安全状态，则让真蛇去吃；若不安全，则跟着蛇尾走（广度优先寻最长路径），没走一步都需进行一次上述判断。注：只要能找到蛇头到蛇尾的路径，则蛇安全。 上述算法仍可能导致蛇进入死循环，则没有安全路径可以吃到食物，该情况发生在大部分食物已经吃完的时候，目前没找到解决办法，若有兴趣或有更好的解法，欢迎联系。

vc编的线性规划源码,单纯形方法求解线性规划问题-vc-compile-source linear programming, simplex method for solving linear programming problems

we propose a generative tracking method based on a novel robust linear regression algorithm. In con- trast to existing methods, the proposed Least Soft-thresold Squares (LSS) algorithm models the error term with the Gaussian-Laplacian distribution, which can be solved ef- ficiently. Based on maximum joint likelihood of parameters, we derive a LSS distance to measure the difference between an observation sample and the dictionary. Compared with the distance derived from ordinary least squares methods, the proposed metric is more effective
