汉诺(hanoi)问题采用递归算法解决，并编制了手动及演示界面

Polimorpich文件加密系统。用delphixe2编程。在没有代码注释的情况下，不要使用AES、rijndael等。

ACM题目，实现两个大数的相乘，题目详见http://acm.zju.edu.cn/show_problem.php?pid=1272-ACM topic, the two realize the multiplication of large numbers, see the topic http://acm.zju.edu.cn/show_problem.php?pid=1272

几个关于汉诺塔算法的C++源代码，对于理解递归算法很有帮助-Tower of Hanoi algorithm on a few of the C++ source code helpful for understanding the recursive algorithm

Recovery phase with recursive Costas loop. Bpsk symbols to demodulate

在数值计算中，一般的牛顿迭代法得到的数值具有截断误差，因此，用VB编写的可是实现任意精度的圆周率的计算程序-in numerical calculation, the general Newton iterative numerical method with the truncation error, therefore, prepared by the VB But to achieve any degree of accuracy the circumference of the rate calculation procedures

生成密码的程序，按照升序模拟不同进制的加法运算。-generated password procedures, in accordance with the simulation of different band ascending the addition operations.

根据已知数据的权重对数据进行拟合，若不能给出数据的权重就默认为数据权重为1.这种拟合 方法是根据最小二乘进行的。-The basis of known data on the weight of the data fitting, if the data should not give the weight for data on the default weight is 1. This method is based on least-squares fitting carried out.

一个计算光子晶体的程序，Fortran语言编写，学习光子晶体方向的很好的参考程序-A procedure for calculating the photonic crystal, Fortran languages, study of photonic crystal the direction of a good reference procedures

用于密码学最最基本的模运算中，或者是说信息安全数学基础中的相关运算。 不仅仅有代码，还有相关的ＰＤＦ文档的说明，希望能对密码学的初学者有帮助。
