一种采用混合策略的改进离子运动算法

摘要

Aiming at overcoming the shortcomings of the ions motion algorithm (IMO),this paper proposed a new improved ions motion algorithm (IIMO).The IIMO depicted new mathematical models of ions motion based on the characteristics of the attraction between the same kind of ions and the repulsion between the different kinds of ions,and the random movement characteristics which ions appeared in the liquid space.In order to test the performance of the IIMO,experiments were carried out on fourteen typical optimization problems,and the experimental results show that the IIMO has faster convergence rate,stronger local search ability and global searching ability than that of the IMO and the PSO.The robustness of the IIMO is stronger than that of the IMO and the PSO.%为了克服离子运动算法(IMO)存在的不足,提出一种新的改进离子运动算法(IIMO).该IIMO算法基于同类离子相互排斥而异类离子相互吸引,以及离子在液态空间中出现随机移动的特征,刻画出一种新的离子运动数学模型.选取14个比较典型的优化问题用来测试IIMO算法的性能.测试结果表明,IIMO算法比IMO和PSO算法具有更快的收敛速度、更强的局部搜索能力和全局搜索能力,IIMO算法的鲁棒性比IMO和PSO算法强.
