非线形回归程序进行最优化.(我上传的五个程序都是我个人做研究中写的,由于时间比较匆忙且只是自己写文章时做的实验,没有什么注释,如果有什么不懂的,可以email联系我:)(non-linear regression procedure optimization. (I uploaded five procedures are my personal study was done, Because of the time compared to just rush and write the article, so the experiment, nothing Notes, if what I do know, I can email links :))

说明：  图论算法用于求解数学中的最短路问题，特别适用于建模编程(Graph theory algorithm for solving the mathematical problem of the most short-circuit, especially suitable for modeling programming)

In this program, a 20 micron x 8 micron platform is taken with closely placed slits emitting light at the upper border of domain which extend only in the third dimension perpendicular to the plane of simulation and which are projected as just point sources in the simulation domain. The region surrounding the waveguide are filled with air of refractive index, n=1.

FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )

应用系统动力学模型，解决在一个封闭的海岛上，对两个群体：1.狐狸(FOXES)；2.啮齿动物（RODENTS）关于生态平衡的问题。详见说明。(With the use of system dynamics model, the program resolves a problem that based on the ecological balance.)

神经网络的使用方法，希望对大家有用，适合有基础的学生自己研究(Use of neural networks, we want to be useful for students who have their own research foundation)

Ant Optimization algorithm

用小波变换对图像进行JPEG压缩编码,尤其是在低比特率时，可以消除块效应。(wavelet JPEGimage compression )
