A new method to adjust weights of BP network is proposed based on quantum particle swarm optimization.This algorithm combines concepts of particle swarm and quantum principles
which overcome the limitations both the local extreme values and bad optimization result of traditional particle swarm optimization algorithm
and get the best-optimized parameters of BP network.The new algorithm is used in simulation of three typical complex functions
results of which are analyzed and compared with that of BP algorithm and BP network optimized based on traditional particle swarm optimization algorithm.Results show the performances of the new algorithm are superior to that of other two kinds of algorithms
