中文说明：粒子群算法的基于迭代技术是用来寻找FIR滤波器设计problem.Genetic算法（GA），粒子群优化（PSO）的最佳解决方案，已经在这里使用的线性相位低通FIR滤波器的设计。改进的粒子群算法，给了一个新的定义为速度矢量和群更新，因此该解决方案的质量比单纯PSO更好
English Description：
particle swarm optimizationAn iterationbased technique is used to find the optimal solution of FIR filter design problem.Genetic algorithm (GA), particle swarm optimization (PSO), has been used here forthe design of linear phase low pass FIR filter. Improved particle swarmoptimization that gave a new definition for the velocity vector and swarm updatingand hence the solution quality is better than simple PSO
