In this paper we propose a new algorithm in solving constrained problem--Adaptive Quantum-behaved Particle Swarm Optimization(AQPSO).The AQPSO outperforms QPSO and PSO in global search ability and local search ability,because the adaptive method is more approximate to the learning process of social organism with high-level swarm intelligence and can make the population evolve *** adopt a non-stationary multi-stage assignment penalty in solving constrained problem to improve the convergence and gain more accurate *** approach is tested on several accredited benchmark functions and the experiment results show much advantage of AQPSO to QPSO and the traditional PSO.
