摘要
红嘴蓝鹊优化算法 (red-billed blue magpie optimizer, RBMO)具有较强的全局搜索和快速收敛能力,但收敛精度较低、局部开发性能不足。针对此问题,提出了一种融合多策略改进的红嘴蓝鹊优化算法(improved red-billed blue magpie optimizer, IRBMO)。首先在迭代早期阶段引入佳点集模型,增加红嘴蓝鹊种群的多样性;其次,利用威布尔分布变异策略优化搜索步长来改进个体的位置更新策略,从而提升算法收敛速度和精度;最后,引入翻筋斗觅食策略,解决算法末期落入局部陷阱而无法获得最优的问题。基于12个基准测试函数进行数值实验,对比6种算法,结果表明该算法明显加快收敛速度、提高搜索精度,取得更优的平均值和标准差,误差相较于改进前平均降低了97.96%。此外,通过IRBMO优化混合核极限学习机(hybrid kernel extreme learning machine, HKELM)模型参数并应用于锂电池荷电状态(state of charge, SOC)预测,结果表明该模型平均绝对误差、均方根误差和平均绝对百分比误差分别降低至0.58%、0.75%和1.06%,进一步验证了该算法的可靠性和有效性。
Abstract
RBMO (red-billed blue magpie optimizer) has strong global search and fast convergence capabilities, but has low convergence accuracy and insufficient local development performance. To address this issue, IRBMO (improved red-billed blue magpie optimizer) fused with multiple strategies was proposed. Firstly, the good nodes set model was introduced in the initial generation stage of the population to increase the diversity of the red-billed blue magpie population in the early stage. Secondly, the Weibull distribution mutation strategy was utilized to optimize the search step size to improve the individual’s position update strategy, thereby enhancing the convergence speed and accuracy of the algorithm. Finally, a somersault foraging strategy was employed to solve the problem of falling into local traps at the end of the algorithm and not being able to obtain the optimal solution. Numerical experiments were conducted based on twelve benchmark test functions, comparing the algorithm with six other algorithms, the results show that the improved algorithm significantly accelerated convergence speed, improved search accuracy, and achieved better mean and standard deviation,the optimal value error was reduced by an average of 97.96% compared to the original algorithm. Furthermore, the IRBMO was applied to optimize the parameters of the HKELM (hybrid kernel extreme learning machine) model for SOC (state of charge) prediction of lithium-ion batteries. The results demonstrate that the mean absolute error, root mean squared error, and mean absolute percentage error of the model are reduced to 0.58%, 0.75%, and 1.06%, respectively, which further verifies the reliability and effectiveness of the proposed algorithm.

总体来说,相比传统优化算法,RBMO具有较强的收敛速度、全局寻优能力和鲁棒性,可以适应多种不同的环境和约束,计算复杂度较低,简单灵活且易于实现。然而,算法在现实应用时依然会存在过早收敛、停滞不前、陷入局部最优的风险,导致精度不高。且提出RBMO时间短,几乎没有其改进算法,为弥补RBMO的缺陷与不足,现融合3种策略提出一种改进红嘴蓝鹊算法(improved red-billed blue magpie optimizer,IRBMO)。首先在迭代早期引入佳点集模型增加红嘴蓝鹊种群多样性;其次,利用威布尔分布变异策略优化搜索步长来改进个体的位置更新策略,从而提升算法收敛速度和精度;最后,引入翻筋斗觅食策略,解决算法末期落入局部陷阱而无法获得最优的问题。通过数值实验,对12个基准函数优化问题的进行仿真,收敛速度与寻优精度均明显提升,证明IRBMO可以解决复杂函数模型的优化问题。
