Quantum-behaved particle swarm optimization (QPSO) is a widely used algorithm for global optimization of multi-dimensional functions. In this paper, a modified and improved QPSO using fitness weighted recombination operator along with a fitness proportionate selection mechanism is proposed. The proposed algorithm is tested on different benchmark functions and compared with the standard Particle Swarm Optimization (PSO) and QPSO. The experimental results show comprehensive superiority of the proposed algorithm.
