From May 2003 to May 2007 he was a postdoctoral fellow at school of mechanical engineering of Dalian University of Technology, Dalian, China, with the direction of stability of delayed neural networks, and from August 2005 to present he is a Professor with the research direction of Intelligent Computing and its Applications at Dalian University, Dalian, China. 1 Introduction The third paper, ‘Research on PSO algorithms for the rectangular packing problem’, by Jinmin Wang, Yang Qi With the rapid development of computer and network and Jing Zhang, researches the search efficiency of the technologies in recent years, research and applications in particle swarm optimisation (PSO) algorithm. Through computer graphics, imaging and image processing, fitting the data to the length of the solution interval and the computer-aided design, computer animation, simulation number of iterations, a strong search capability for the PSO and modelling receive an increasing attention from was proved. The results of experiments with comparisons of researchers across the world. Continual, pioneering research many disturbance strategies showed that a stochastic is essential to further promote the development of those strategy was beneficial for raising the search capability of areas to benefit their applications in various fields.
