AI总结:

本文提出改进海马优化器 mSHO,通过三步局部搜索策略增强开发能力,在 CEC'2020 测试函数中排名第 1,并在多个工程优化问题上取得最佳结果。

摘要:

海马优化器(Sea Horse Optimizer, SHO)是一种值得关注的元启发式算法,它模拟海马表现出的多种智能行为,包括摄食模式、雄性繁殖策略以及复杂的运动模式。为了模仿海马精细的运动方式,SHO 融合了对数螺旋方程和 Levy 飞行,从而有效地结合了具有较大步长的随机移动与精细的局部开发。此外,布朗运动的利用有助于对搜索空间进行更全面的探索。本研究引入了 SHO 算法的一个鲁棒且高性能的变体,命名为 mSHO。该改进主要侧重于增强 SHO 的开发能力,通过用一种创新的局部搜索策略替换其原有方法,该策略包含三个不同的步骤:基于邻域的局部搜索、基于全局非邻域的搜索,以及一种环绕现有搜索区域的方法。这些技术提升了 mSHO 算法的搜索能力,使其能够有效地在搜索空间中导航并收敛到最优解。全面的结果明确确立了 mSHO 方法在应对一系列优化难题时作为典范工具的优越性和效率。结果表明,所提出的 mSHO 算法在 CEC'2020 测试函数上获得了总排名第 1。相比之下,mSHO 在工程问题上取得了最佳值,在压力容器设计、减速器设计、拉伸/压缩弹簧、焊接梁设计、三杆桁架工程设计、工业制冷系统、多产品批量工厂、悬臂梁问题、多盘离合器制动器问题上分别记录到的值为 0.012665、2993.634、0.01266、1.724967、263.8915、0.032255、58507.14、1.339956 和 0.23524。

英文摘要:

Sea Horse Optimizer (SHO) is a noteworthy metaheuristic algorithm that emulates various intelligent behaviors exhibited by sea horses, encompassing feeding patterns, male reproductive strategies, and intricate movement patterns. To mimic the nuanced locomotion of sea horses, SHO integrates the logarithmic helical equation and Levy flight, effectively incorporating both random movements with substantial step sizes and refined local exploitation. Additionally, the utilization of Brownian motion facilitates a more comprehensive exploration of the search space. This study introduces a robust and high-performance variant of the SHO algorithm named mSHO. The enhancement primarily focuses on bolstering SHO's exploitation capabilities by replacing its original method with an innovative local search strategy encompassing three distinct steps: a neighborhood-based local search, a global non-neighbor-based search, and a method involving circumnavigation of the existing search region. These techniques improve mSHO algorithm's search capabilities, allowing it to navigate the search space and converge toward optimal solutions efficiently. The comprehensive results distinctly establish the supremacy and efficiency of the mSHO method as an exemplary tool for tackling an array of optimization quandaries. The results show that the proposed mSHO algorithm has a total rank of 1 for CEC'2020 test functions. In contrast, the mSHO achieved the best value for the engineering problems, recording a value of 0.012665, 2993.634, 0.01266, 1.724967, 263.8915, 0.032255, 58507.14, 1.339956, and 0.23524 for the pressure vessel design, speed reducer design, tension/compression spring, welded beam design, three-bar truss engineering design, industrial refrigeration system, multi-Product batch plant, cantilever beam problem, multiple disc clutch brake problems, respectively.
