K短路算法的C++程序C++程序实现 K短路径问题 K短路径问题是图论研究中的一个经典算法问题， 旨在寻找图（由结点和路径组成的）中两结点之间的K短路径

并行编程中Monte Carlo方法求π值的程序说明（具体采用MPI＋C语言实现）-Parallel programming methods in the Monte Carlo description of the procedures seek π value (specific language using MPI C)

visual fortran常用数值算法集及源代码  何光渝，高永利 (作者) 共有fortran子程序近200个，包含各种算法。程序均经过验证.  

本代码为是以链表为数据结构，组织的一种多项式求和小实验，用户输入多项式的系数和指数，计算后输出结果。对于刚接触链表结构的同学，是一个很好的理解和锻炼的实验.

曲线拟合小工具，包括对数拟合，多项式拟合，直线拟合，指数拟合，乘幂拟合-Curve fitting of small tools, including on the number of fitting, polynomial fitting, straight fitting, exponential fitting, by fitting power

求素数，并且保存于文本文件，并且下次执行还可以接着上次的结果继续找下去 所以总有一天你会找到最大的素数……每天就像挂Q一样挂一下这个程序就行了-Seek primes, and stored in a text file, and the next performance can also be followed by the last results continue to look down so that one day you will find the largest prime number ... ... the same day, just hanging Q hang about this program on the list ... ...

空间八节点实体单元的有限元三维计算程序,通用性较好-Eight-node solid element space of three-dimensional finite element program, GM is better

系统辨识中，一个很重要的方法是用相关分析法辨识脉冲响应，该程序可以计算出输入和输出序列的互相关函数，以及计算出脉冲响应估计值-system identification, a very important way is to analyze the identification impulse response, the program can calculate the input and output sequence of cross-correlation function, and calculated the estimated value of the impulse response
