Abstract: The basic particle swarm optimization algorithm is identified as five types of PSO according to its cognition component and social component value，such as PSO Full-Model，PSO Cognitive-Only Model，PSO Social-Only Model，PSO Selfless Model and PSO Selfless Full-model.Compare five PSO models’ effectiveness and efficiency according to their success rate，average function evaluation and their best fitness by applying parameter set and using five benchmark functions.The result is that Full-Model and Selfless Full Model with K are effective in solving the functions with high dimension，Social Model and Selfless Model without K are also effective in solving the functions with less dimension such as Schaffer function.
