有限域上计算的基本库

著名的十五难题是用A*（A星）算法解决的。这是一个用C#（C Sharp）编程语言编写的windows应用程序。

用c++实现的对字符串和任意文件的加密解密算法，加密和解密方式可以选择，能够显示16轮变换的输入输出 和子密钥，实现对文件的加密解密时需把 文件放在相应目录下。运行界面设计良好，压缩包内含有测试通过的 可执行文件。在VisualC++6.0中测试通过。                                                                  

这是一些数值算法的源程序，包括非线形方程的解法。(二分法，牛顿法)。线性代数方程组数值解法（包括，消去法，迭代法）-This is some numerical algorithm of the source, including non-linear equations method. (Dichotomy, Newton). Linear algebra equations Numerical Solution (including, elimination, iteration)

The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F. Determine the dynamic equations of motion for the system, and lin earize about the pendulum s angle, theta = Pi (in other words, assume that p endulum does not move more than a few degrees away from the vertical, chosen to be at an angle of Pi). Find a controller to satisfy all of the design re quirements given below. -The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F.
