| 摘 要： | 针对免疫算法(AIA)的运行速度和收敛速度慢的缺点,提出一种精英交叉策略,并将精英交叉策略与基于欧氏距离的免疫算法相结合,得到一种基于欧氏距离和精英交叉的免疫算法(DKBAIA).提出了抗体相似矩阵的概念和一种改进的措施,对DKBAIA进行改进,从而得到改进的DKBAIA算法(MDKBAIA).仿真结果表明,精英交叉策略对免疫算法的收敛性能有显著的改善;MDKBAIA的运行速度也得到极大的提高,已接近GA的运行速度.

| Abstract: | To the drawback that artificial immune algorithm (AIA) usually runs slowly and its convergent speed is also slower than genetic algorithm (GA), a king-crossover strategy is proposed. Combining the king-crossover strategy with Euclidean distance based AIA, a novel AIA based on Euclidean distance and king crossover strategy (DKBAIA) is derived. The concept of similar antibody matrix and an improving measure are proposed to improve the DKBAIA, thus the improved DKBAIA (MDKBAIA) is obtained. Simulation results show that the convergence performance of MDKBAIA is improved greatly, its running speed is also enhanced greatly, which is nearly close to the speed of GA. |
