Abstract

Gaussian bare-bones differential evolution GBDE is a new DE algorithm which employs Gaussian random sampling to generate mutant vectors. Though this method can maintain population diversity and enhance the global search ability, it may result in slow convergence rate. In this paper, we present an improved GBDE IGBDE algorithm by using neighbourhood mutation to accelerate the evolution. Moreover, a modified parameter control method is utilised to adjust the crossover rate CR. To verify the performance of our approach, 13 well-known benchmark functions are tested in the experiments. Simulation results show that IGBDE outperforms the original GBDE in terms of solution accuracy and convergence speed.
