Abstract

In this paper, a modified quantum-behaved particle swarm optimization (QPSO) method is proposed to solve the problem. The proposed method, denoted as RPQPSO, combines the QPSO algorithm with random perturbation operation to enhance the global search ability of the algorithm. The perturbation strategy adopts two methods to perturb each particle in the group according to the random probability at the late stage of evolution, so that the algorithm avoids falling into the local optimum. The simulation results show that the proposed RPQPSO method is able to obtain higher quality solutions in the ED problem than any other tested optimization algorithm.
