The teaching-learning-based optimization (TLBO) algorithm, which has gained popularity among scholars for addressing practical issues, suffers from several drawbacks including slow convergence speed, susceptibility to local optima, and suboptimal performance. To overcome these limitations, this paper presents a novel algorithm called the teaching-learning optimization algorithm, based on the cadre-mass relationship with the tutor mechanism (TLOCTO). Building upon the original teaching foundation, this algorithm incorporates the characteristics of class cadre settings and extracurricular learning institutions. It proposes a new learner strategy, cadre-mass relationship strategy, and tutor mechanism. The experimental results on 23 test functions and CEC-2020 benchmark functions demonstrate that the enhanced algorithm exhibits strong competitiveness in terms of convergence speed, solution accuracy, and robustness. Additionally, the superiority of the proposed algorithm over other popular optimizers is confirmed through the Wilcoxon signed rank-sum test. Furthermore, the algorithm's practical applicability is demonstrated by successfully applying it to three complex engineering design problems.
基于教学的优化(TLBO)算法在解决实际问题方面受到学者们的欢迎,但它存在一些缺点,包括收敛速度慢、易陷入局部最优以及性能次优。为克服这些局限性,本文提出了一种基于干群关系与导师机制的新型算法——教学学习优化算法(TLOCTO)。该算法在原有教学基础上,融入了班干部设置和课外学习机构的特点。它提出了一种新的学习者策略、干群关系策略和导师机制。对23个测试函数和CEC - 2020基准函数的实验结果表明,改进后的算法在收敛速度、解的精度和鲁棒性方面具有很强的竞争力。此外,通过威尔科克森符号秩和检验证实了该算法相对于其他流行优化器的优越性。此外,通过将该算法成功应用于三个复杂工程设计问题,证明了其实际适用性。
