java程序实现基本粒子群算法，本程序适应于演化算法的初学者，简单易懂，清晰明了。-Java program to achieve the particle swarm algorithm。This procedure to adapt to evolutionary algorithms for beginners

粒子群优化算法的JAVA实现,说明：算法为了演示功能，所以没有优化，没有异常处理等，仅作演示用。-Particle swarm optimization algorithm JAVA, Descr iption: Algorithms for presentation capabilities, so no optimization, no exception handling, etc., only for demonstration purposes.

大部份的优化问题都是多峰函数或病态函数，为了克服基本粒子群算法的缺陷，我研究了以下四种改进的粒子群算法(Most optimization problems are multi-peak functions or ill-conditioned functions. In order to overcome the defects of basic particle swarm optimization, I studied the following four improved particl
