Aiming at the disadvantages of the particle swarm optimization( PSO) algorithm
such as poor diversity
premature convergence and weak robustness
a multi-swarm PSO algorithm based on parallel structure is proposed.On the basis of the basic PSO
the parallel multi-swarm algorithm adapts two updating formulas which can accelerate and slow down the particle movement respectively
which not only improves the poor population diversity of PSO
but also ensures the computational precision of the algorithm. Ten typical benchmark functions are used for simulation of the proposed algorithm. The results show that compared with the basic PSO algorithm
the multiswarm PSO algorithm based on the parallel structure has faster convergence speed and shorter operation time.
