Abstract
Differential evolution is a population-based optimisation algorithm and has been successfully applied in many fields. However, when tackling large-scale optimisation problem, it still encounters serious challenges. To meet these challenges, a dynamic differential evolution with oppositional orthogonal crossover is proposed in this paper. A new oppositional learning is proposed and then it is used in the orthogonal crossover to improve the exploitation ability of the dynamic differential evolution. During the evolution process in dynamic differential evolution, only one individual is randomly chosen to undergo this oppositional orthogonal crossover operation. Thirteen benchmark problems with 1,000 dimensions were used to evaluate its performance. The results show that the proposed method is very competitive in terms of solution quality obtained.
