Abstract
Linear acceleration coefficients adjustment had been widely used in particle swarm optimization (PSO). In this paper, a novel nonlinear strategy is developed, where the acceleration coefficients including both cognitive component and social component are adjusted nonlinearly to improve the optimization performance within a reasonable iteration times. Furthermore, the novel adjustment is deeply analyzed by experimental simulations based on four standard test functions. The results confirm the validity of the nonlinear parameter adjustment method in terms of the balance between convergence rate and optimization accuracy.
