— Quantum-behaved particle swarm optimization (QPSO) algorithm has shown an effective performance for solving variant benchmark and real-world optimization problems. However, it suffers from premature convergence because of quick losing of diversity. In order to enhance its performance, this paper proposes a new algorithm, called DCSQPSO, which employs a diversity-controlled into QPSO enhancing mechanism and local search strategies to improve the solution quality. A comprehensive experimental study is conducted on a set of benchmark functions, Comparison results show that DCSQPSO obtains a promising performance on the majority of the test problems.
