In order to further improve the accuracy of Quantum Particle Swarm Optimization algorithm, the evaluation method of δ trap characteristic length L(t) of wave function for describing the particle’s state is modified. Introducing a random weight to each particle in swarm, and generating a random -weighed mean best position to reassess L(t) , enhance the algorithmic randomness, help algorithm to escape from local minima to manacle, make the algorithm to find the global extreme points. Through the test of several typical functions, its result shows that the convergence accuracy of the improved algorithm is better than QPSO algorithm’s, and it can be very strong to avoid falling into local extremums.
