应用基本粒子群算法求解复杂连续函数优化问题(Application of Basic Particle Swarm Optimization to Complex Continuous Function Optimization)

Code for Classification of points

说明：  集合卡尔曼滤波(EnKF) 数据同化方法可以避免了EKF 中协方差演变方程预报过程中出现的计算不准确和关于协方差矩阵的大量数据的存储问题,最主要的是可以有效的控制估计误差方差的增长,改善预报的效果。(Ensemble Kalman Filter (EnKF) data assimilation methods can be avoided in the EKF covariance forecasting the evolution equation arising in the course of the calculation is not accurate and on the covariance matrix of a large amount of data storage problems, the most important and effective control can be estimated error variance of the growth, improvement in forecasting results.)

针对多期随机规划问题，利用情景树方法来求解(For multi-period stochastic programming problems, the use of scenarios to solve Tree)

短时傅立叶变换及其反变换---绝对可运行！(Short-time Fourier transform and its inverse transform- absolutely can run!)

SPH方法计算二维溃坝问题的源程序，个人觉得还可以(Two-dimensional dam break problem SPH method the source, individuals felt that I could)

最小二乘拟合的matlab程序，用于数据处理。简单，易懂(The least squares fitting matlab program for data processing.Simple, easy to understand)

计算一般的mie散射光强等参数的精确程序，得到muller矩阵的各个元素表达式(scattering of Mie)

用Wolf法计算lorenzeq混沌系统的Lyapunov指数谱。改变混沌系统参数，计算准确，运行let.m文件，即可计算Lyapunov指数谱 (Wolf Law lorenzeq chaotic systems Lyapunov exponent spectrum. Change the chaotic system parameters, calculated accurate, run let.m file, you can calculate the Lyapunov exponent spectrum)

用Roe格式求解黎曼激波管问题的Fortran源代码。可以通过MUSCL插值来提高求解精度。适合计算流体力学的初学者参考学习。(Riemann shock tube problem with Roe scheme. You cam improve the accuracy by MUSCL interpolation. This code is suitable for CFD beginners.)
