摘　　要：针对雪豹优化算法在求解复杂优化问题时,存在全局勘探能力不足、寻优精度低等问题,提出一种改进的雪豹优化算法。首先,基于分段Logistic混沌映射初始化从而提高初始种群多样性;其次,引入非线性比例因子用于平衡算法的全局勘探能力和局部开发能力;然后,提出了一种差分变异策略,在第一次种群更新位置后,使用5个随机个体提高全局搜索能力和算法收敛能力,在第二次种群更新位置后,使用3个随机个体保证在求解过程的中后期也具有一定的全局勘探能力,尽可能避免陷入局部最优。通过在IEEE CEC2022基准函数测试集上测试,并与其他算法进行比较,结果表明所提出的算法在种群质量、求解精度以及算法稳定性上均有较大提升。最后将所提出的算法应用于工程优化,计算结果进一步证实了算法的强优化能力。An improved snow leopard optimization algorithm is proposed to solve complex optimization problems,such as insufficient global exploration ability and low optimization accuracy.Firstly,the initial population diversity is improved based on piecewise Logistic chaotic mapping initialization.Secondly,a nonlinear scaling factor is introduced to balance the global exploration ability and local development ability of the algorithm.Then,a differential variation strategy is proposed.After the first population update position,five random individuals are used to improve the global search ability and the convergence ability of the algorithm.After the second population update position,three random individuals are used to ensure the global exploration ability in the middle and late period of the solution process,so as to avoid falling into the local optimal as much as possible.The proposed algorithm is tested on IEEE CEC2022 benchmark function test set and compared with other algorithms.The results show that the proposed algorithm has great improvement in population quality,solving accuracy and algorithm stability.Finally,the proposed algorithm is applied to engineering optimization,and the calculation results further confirm its strong optimization ability.
