粒子群优化算法

这个程序分别用二分法，Newton法，弦截法，Newton下山法等算法求解非线性方程-this procedure were used dichotomy, Newton, String interception, Newton downhill law for solving nonlinear equations

这是PSO算法功能，给每一位想要轻松地学习。此功能有许多选项，给你更好的和最佳的输出。

黑洞的算法，和二分法，我写的，嗲给知道一些，自己感觉还可以。-Black hole of algorithms, and the dichotomy, I wrote some satay to know that they feel can also.

在inuxl ubantu系统下的QT运行，一个简单的c++绘图板的编制，能够满足正常情况下的图形的绘制

素数环： 把从1到10这10个数摆成一个环，要求相邻的两个数的和是一个素数。 〖问题分析〗 这是一道回溯的题目。从1开始，每个空位有9种可能，每种可能加入约束条件即可 1.与前面所有的数不重复 2.与前一个数和为素数（最后一个和第一个也要满足）。 〖算法流程〗 1、数据初始化； 2、递归填数： 判断第J种可能是否合法；  A、如果合法：填数；判断是否到达目标（10个已填完）： 是，打印结果；不是，递归填下一个；  B、如果不合法：选择下一种可能；-Prime Central: 1-10 from 10 the number of put this into a ring, asked the two adjacent numbers and is a prime number. 〗 〖Analysis is a retrospective this topic. From 1 year, 9 out of every space possible, each may be bound by the conditions of accession to 1. And in front of all the number of non-repetition, 2. With a few and for a prime number (the last and the first to meet). 1〗 〖algorithm processes the data to initialize 2, fill in the number of recursion: first to determine the legality of J possible A, if the legitimate: the number of Reclamation to determine whether the target (10 have been completed): Yes, print the results of not, fill in the next recursive B, if not legitimate: a possible alternative

The source includes a recursive template version and a non-recursive template version

我提出了一个伪谱的显式方案，可以模拟低频电磁 （EM） 传播在地球。该方案解决了线性周期抛物型方程， 具有内机精度精密，两个时间和空间。
