简单的粒子群算法，matlabR2010b测试可以使用，对于初学者是很好的程序(Simple particle swarm optimization algorithm, the matlabR2010b test can be used, for beginners is a very good program.)

介绍关于MATLAB的基础知识，运算法则，函数等等.(About the MATLAB basics, algorithms, functions, and so on.)

说明：  利用遗传算法求解带约束的优化问题，可以直接运行，修改目标函数即可(Solving constrained optimization problems by genetic algorithm)

Absorbing Boundary Conditions in Free Space

说明：  抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)
