Crazy Flocking 3D Birds by Ira Greenberg. Simulates a flock of birds using a Bird class and nested pushMatrix() / popMatrix() functions. Trigonometry functions handle the flapping and sinuous movement.

一个pso程序的源代码。在vc.net2003下面通过。 建议：看代码之前，请先弄明白pso是怎么回事。然后请对应着来：程序中用Agent代表一只鸟，PSO代表鸟群。阅读源代码，不要顺着看，先看main(),然后按照出现的东西的顺序，一个一个得来，呵呵，纯粹是建议。 pso程序的源代码-A pso program' s source code. Vc.net2003 following through. Recommendation: Before looking at th

PSO is originally attributed to Kennedy, Eberhart and Shi[1][2] and was first intended for simulating social behaviour,[3] as a stylized representation of the movement of organisms in a bird flock or fish school. The algorithm was simplified and it w

SO算法就是模拟一群鸟寻找食物的过程，每个鸟就是PSO中的粒子，也就是我们需要求解问题的可能解，这些鸟在寻找食物的过程中，不停改变自己在空中飞行的位置与速度。大家也可以观察一下，鸟群在寻找食物的过程中，开始鸟群比较分散，逐渐这些鸟就会聚成一群，这个群忽高忽低、忽左忽右，直到最后找到食物。这个过程我们转化为一个数学问题。寻找函数　 y=1-cos(3*x)*exp(-x)的在[0,4]最大值。(SO algorithm is the simulation of a flock of birds f
