Elite particle swarm optimization algorithm and its application in robot path planning
To overcome the shortcomings of standard Particle Swarm Optimization (PSO) algorithm that is easy to trapp into a local optimum
the improved PSO was proposed based on the standard PSO. By inducing the renewal functions and a best selecting strategy
the improved algorithm could keep the fast convergence speed and reduce the possibility of trapping into a local optimum. As compared the standard PSO
the improved algorithm not only enlarges the searing space but also shows lower complexity. Obtained results prove that the algorithm is easy to be induced and has a higher global searching ability in high efficiency and better robustness. The improved algorithm was applied to solving the robot path planning problem. The simulation experiments show that the improved algorithm can get more accurate path in the robot path planning and its calculation time can reduced by 15% as compared with that of traditional methods. These results prove the feasibility and efficiency of the improved algorithm.
