针对鲸鱼优化算法(Whale Optimization Algorithm,WOA)存在的收敛速度慢、精度低的问题,提出了基于Tent混沌精英和Lévy飞行策略的鲸鱼优化算法(TELWOA).使用Tent混沌映射初始化鲸鱼种群,保持种群的多样性,并通过引入精英反向学习策略,对初始种群的精英个体生成反向解,选取适应度高的种群作为下一代鲸鱼种群,加快算法收敛速度.其次,通过使用非线性收敛因子,缓解算法全局搜索和局部搜索能力不平衡的现象.最后,在鲸鱼位置寻优过程中使用Lévy飞行策略,避免算法陷入局部最优,提升算法的全局搜索能力.通过对不同改进策略的有效性分析、与其他智能算法的对比分析,证明了 TELWOA算法在收敛精度、算法稳定性和全局寻优能力上与对比算法有显著提升,具有一定的实际工程应用能力.
Whale Optimization Algorithm Based on Chaotic Elite and Lévy Flight Strategy
For the problems of slow convergence and low accuracy of Whale Optimization Algorithm(WO A),the WO A based on Tent chaotic Elite and Lévy flight strategy(TELWOA)is proposed.The whale population is initialized by Tent chaotic mapping to maintain the population diversity,and the algorithm convergence speed is accelerated by introducing an elite opposition-based learning strategy to generate the inverse solution for the elite individuals of the initial population and select the population with high adaptation as the next generation whale population.Secondly,by using a nonlinear convergence factor,the imbalance between the algorithm's global search and local search ability is alleviated.Finally,the Lévy flight strategy is used in the whale location search process to avoid the algorithm from falling into local optimum and to improve the global search ability of the algorithm.By analyzing the effectiveness of different improvement strategies and comparing with other intelligent algorithms,it is proved that TELWOA has significant improvement in convergence accuracy,algorithmic stability and global optimization searching ability with comparison algorithms,and it has certain practical engineering application ability.
