c写的随机数生成程序，很实用，跨平台，可以在Linux下编译，也可以改成在windows下下编译

1.求解像素点在水平方向的梯度 2.求解像素点在垂直方向的梯度 3.生成高斯滤波w(s,t)          4.用高斯模板对图像进行相关运算（线性滤波） 5.针对每个像素点（i,j),计算矩阵M 6.如果R(i,j)是3*3邻域内的极大值，且大于阀值，则选为角点 7.统计角点个数 8.确定角点位置           

A*算法解决八数码问题，最小优先队列结合DFS结合全排列hash结合A* 算法 f(n) = g(n) + h(n)解决八数码问题。全排列hash就是常说的康拓判重。

用BP网络建立映射关系，为遗传算法提供适应度函数，通过改进遗传算法完成最小值优化-the mapped relation is built using BP network in order to provide fitness function for genetic algorithm. At last, optimization of minimum value is finished by genetic algorithm.
