利用VC++编写的一个粒子系统，各种小键盘控制粒子的运行方式，各种外观。-Written in VC++ using a particle system, a variety of small particles keyboard operation mode, a variety of appearance.

此為應用MATHCAD來編寫BPSO，為粒子群優演算法，可應用於求解最佳化過程，可跑小系統之模擬，簡單又好用-This is the application to write MATHCAD BPSO, particle swarm optimization algorithm can be applied to solve the optimization process, the simulation can run a small system, simple and easy to us
