| 摘 要: 针对白骨顶鸡优化算法(COOT)全局搜索能力差、优化精度低和易陷入局部最优等缺陷,提出了一种融合翻筋斗觅食和正余弦策略的白骨顶鸡优化算法,引入一种翻筋斗觅食策略,增加了白骨顶鸡个体的多样性。此外,在领导者位置更新过程中采用正余弦策略和随机因子,以提高算法的搜索能力。通过10个标准检验函数,以及Wilcoxon秩和检验,对改进的COOT性能进行了全面评估,并将其与其他几种算法进行了比较。仿真结果表明,改进的COOT在迭代速度和收敛精度方面取得了显著的提升,并展现了出色的鲁棒性。 |

| Abstract: Aiming at the limitations of the Coot Optimization Algorithm (COOT) in terms of poor global search ability, low optimization accuracy, and susceptibility to getting stuck in local optima, a COOT algorithm integrating somersault foraging and sine-cosine strategy is proposed. This algorithm integrates somersault foraging and sine cosine strategy. By introducing a somersault foraging strategy, the individual diversity of the COOT bird is increased. Additionally, sine-cosine strategy and a random factor are employed during the leader position update process to enhance the algorithm's search capability. The performance of the improved COOT is comprehensively evaluated using ten standard benchmark functions and the Wilcoxon rank sum test, and the results are compared with several other algorithms. Simulation results indicate that the improved COOT has achieved significant enhancements in iteration speed and convergence accuracy, demonstrating excellent robustness. |
