程序提出了一种基于人群混合算法，是粒子群优化和引力搜索算法的组合。主要目标提高整合PSO和GSA算法的能力-Hybrid Particle Swarm Optimization and Gravitational Search Algorithm (PSOGSA) A new hybrid population-based algorithm (PSOGSA) is proposed with the combination of Particle Swarm Optimization

第7章 基于人群搜索算法的PID参数整定，代码完整好使。(In Chapter 7, PID parameters are adjusted based on crowd search algorithm, and the code is complete.)
