School of Information Science ＆ Technology, Jiujiang University, Jiujiang Jiangxi 332005, China ; 2. State Key Lab of Software Enginee- ring, Wuhan University, Wuhan 430072, China） Differential evolution is simple and efficient. However,when solving the large-scale optimization problems,the performance decreases rapidly. To overcome this problem,this paper proposed a hybridization differential evolution algorithm of orthogonal crossover and opposition-based learning. In the hybrid algorithm,it used orthogonal crossover to enhance the exploitation ability and adopted opposition-based learning to adjust the diversity of population. Thus it could balance the local and global search ability efficiently. It tested the new algorithm on 11 standard benchmark problems and compared with other four famous variants of differential evolution. The resul |
