Abstract: This paper presents a novel variant of quantum mechanics inspired Particle Swarm Optimisation (PSO) algorithm named constrained/unconstrained Quantum Particle Swarm Optimisation (CQPSO). The proposed algorithm has the properties of quantum mechanics embedded in the structure of the PSO along with the presence of a quadratic interpolation recombination operator. The performance of CQPSO is validated on three standard non linear, unconstrained functions, eight constrained benchmark problems and two constrained, real life, electrical design problems. The experimental results show that the presence of quadratic interpolation recombination operator enhances the performance of quantum mechanics inspired PSO.

Keywords: quantum PSO; particle swarm optimisation; quantum behaviour; quadratic interpolation; constrained optimisation; electrical design; quantum mechanics; global optimisation.
