Particle Swarm Optimization（PSO） theory is introduced. The problem of random number generating with speed renewal in PSO is researched. Three generating ways of random number in speed renewal process are numerically studied in detail by using standard test functions, and the results are explained by corresponding theories. It is helpful to understand the mechanism of PSO algorithm, and also provides the values foundation for further research.
