Abstract To improve the convergent performance of particle swarm optimization(PSO), an adaptive cognitive domain particle swarm optimization(ACDPSO) method is proposed. In the updating equations of particles, the current best position, which the particle achieves, is determined by the center of the best calculated position and the cognizant direction of the particle. Linear decreasing inertia weight is used to optimize particles. Three different PSOs, particle swarm with constant weight(CWPSO), linear decreasing inertia weight PSO(LDWPSO) and Ladder PSO(LPSO), are combined with the proposed method to test the performance of the proposed method, and the results indicate that the proposed method is effective.
