【Abstract】 This paper presents a real-coded hybrid algorithm that contains two search models(the global and local search models) and applies orthogonal crossover to solutions produced by the genetic operators.On the one hand,the hybrid algorithm provides global search(reliability) by means of the promotion of high levels of population diversity.On the other hand,the orthogonal crossover exploits the self-adaptive capacity of real-parameter crossover operators with the aim of producing an effective local tuning on the solutions(accuracy).Experimental results show that,for a wide range of problems,the method we propose here consistently outperforms simple genetic algorithms which appear in the literature.更多还原
