代码说明：

有用的matlab有限分析方法 fd:d=fd(p)，p=[x y],fd为给定任一点到边界的有符号距离函数，负号表示在区域内，正号为在区域外% fh:就是网格大小的函数% h0:也就是h, 网格的初始大小% box:最大外围矩形范围% Input, integer ITERATION_MAX, the maximum number of iterations.% iteration_max:允许的最大迭代次数% pfix：网格中需要固定的点坐标，也就是一定需要出现在网格中的点% Input, VARARGIN, aditional parameters passed to FD and FH.%% p:网格点的x,y坐标% Output, integer T(NT,3), the triangle indices.% t:输出网格任意一个三角形的三个顶点% Local parameters:% Local, real GEPS, a tolerance for determining whether a point is "almost" inside% the region. Setting GEPS = 0 makes this an exact test. The program currently% sets it to 0.001 * H0, that is, a very small multiple of the desired side length% of a triangle. &nbs

说明：首先介绍一下早期的简单模型，即Boid（Bird-oid）模型。这个模型是为了模拟鸟群的行为而设计的，它也是粒子群优化算法的直接来源。(Because the simulation is too simple and far away from the real situation, a random variable is added to the velocity term, that is, in each iteration step, in addition to meeting the "nearest neighbor velocity matching", a random variable is added to each step of the speed, so that the whole simulation looks more realistic.)
