说明：  差分粒子群算法是一种新的模仿鸟类群体行为的智能优化算法，现已成为进化算法的一个新的重要分支。在基本粒子群算法和改进粒子群算法原理的基础上，实现了粒子群算法在函数优化、图像压缩和基因聚类中的应用。(Differential particle swarm optimization (DPSO) is a new intelligent optimization algorithm which imitates the behavior of bird swarm. It has become a new important branch of evolutionary algorithm. Based on the basic particle swarm optimization (PSO) algorithm and the improved principle of PSO, the application of PSO in function optimization, image compression and gene clustering is realized.)
