贪心算法解决部分背包问题

这是代码 Hough 变换，其中 detecs 盘旋而通过定义的半径、 阈和三角洲的图像。它可以被用于带圆圈或非盘旋的功能，通过设置正确的阈限。当你降低门槛时，圈子，你正在寻找光流。我希望，它会对你有用

编程，输入正整数n，求n的阶乘。 编程，统计字符串中数字字符的个数。 打印出水仙花数。 编程，判断字符串是否为回文。 编程，判断正整数n是否为完数。

有限元的分析程序，对于初学有限元在结构中的应用很好用-Finite element analysis program for learning the structure of finite element in the application of good use

Differential evolution: A simple and efficient heuristic for global optimization over continuous spaces. This code implements a basic multi-objective optimization algorithm based on Diferential Evolution (DE) algorithm. When one objective is optimized, the standard DE runs; if two or more objectives are optimized, the greedy selection step in DE algorithm is performed using a dominance relation.

这是老师布置的工程实践的作业， 有很好的参考价值， 代码都有注释。值得分享。

函数

这是基于MFC的sift算法，在VC上运行通过，代码注释比较详细，分块比较清晰，通过按键可以生成高斯金字塔，差分金字塔特征点和方向，已经特征点的文档

解非线性方程组的一种方法：先用一种优化方法将给定初值（它有可能会使得后续的牛顿法发散）通过一条比较快的途径收敛到精确解附近，得到一个新的初始点，然后再通过牛顿法将新的初始点迭代到精确解（一定的误差范围内）。这种方法的优点在于：它可以将牛顿法快速收敛的优势发挥出来，同时又避免了该方法收敛域比较窄的缺点。-solving nonlinear equations in a way : by using a method of optimizing initial Givens (it might make follow-up to Newton"s law divergence) adopted a relatively fast convergence to the channel near the exact solution, to be a new starting point, and then Newton"s law of the new iteration of the initial point of the exact solution ( some of error). This method has the advantage : it can be rapid convergence of Newton"s method to exploit the advantages while avoiding convergence of the method is relatively narrow domain shortcomings.
