AI总结:

针对 FDO 变体在代理数量少时精度低及依赖搜索代理数量的问题,提出 M-IFDO,通过更新侦察蜂位置并移除对齐和凝聚力参数,在基准函数和工程问题上优于多种先进算法。

摘要:

适应度依赖优化器(FDO)被认为是一种新颖的群体智能算法。近年来,FDO 已被多次增强以提升其能力,其中一项改进被称为改进的 FDO(IFDO)。然而,根据研究结果,FDO 的变体受到两个已识别的主要限制的约束。首先,如果使用的代理数量低于五个,则会显著降低算法的精度。其次,FDO 的有效性与所使用的搜索代理数量密切相关。为了克服这些限制,本研究提出了一种改进版的 IFDO,称为 M-IFDO。该改进通过将侦察蜂的位置更新到 IFDO 中来实现,以移动侦察蜂,从而获得更好的性能和最优解。更具体地说,IFDO 中的两个参数,即对齐和凝聚力,被移除,取而代之的是 Lambda 参数被放置在对齐和凝聚力的位置。为了验证新提出算法的性能,M-IFDO 在 19 个基本基准函数、10 个 IEEE 进化计算大会(CEC-C06 2019)问题以及五个现实世界问题上进行了测试。M-IFDO 与五种最先进的算法进行了比较:改进的适应度依赖优化器(IFDO)、改进的多目标差分进化算法(IMODE)、混合采样进化策略(HSES)、基于线性成功历史参数自适应的差分进化算法(LSHADE)以及集成了偶尔重启策略、增加种群规模和迭代局部搜索的 CMA-ES(NBIPOP-aCMAES)。验证标准基于算法达到收敛的程度、内存使用情况和统计结果。结果表明,在基准函数和五个现实世界问题的多个案例中,M-IFDO 超越了其竞争对手。

英文摘要:

Fitness dependent optimizer (FDO) is considered one of the novel swarm intelligent algorithms. Recently, FDO has been enhanced several times to improve its capability. One of the improvements is called improved FDO (IFDO). However, according to the research findings, the variants of FDO are constrained by two primary limitations that have been identified. Firstly, if the number of agents employed falls below five, it significantly diminishes the algorithm's precision. Secondly, the efficacy of FDO is intricately tied to the quantity of search agents utilized. To overcome these limitations, this study proposes a modified version of IFDO, called M-IFDO. The enhancement is conducted by updating the location of the scout bee to the IFDO to move the scout bees to achieve better performance and optimal solutions. More specifically, two parameters in IFDO, which are alignment and cohesion, are removed. Instead, the Lambda parameter is replaced in the place of alignment and cohesion. To verify the performance of the newly introduced algorithm, M-IFDO is tested on 19 basic benchmark functions, 10 IEEE Congress of Evolutionary Computation (CEC-C06 2019), and five real-world problems. M-IFDO is compared against five state-of-the-art algorithms: Improved Fitness Dependent Optimizer (IFDO), Improving Multi-Objective Differential Evolution algorithm (IMODE), Hybrid Sampling Evolution Strategy (HSES), Linear Success-History based Parameter Adaptation for Differential Evolution (LSHADE) and CMA-ES Integrated with an Occasional Restart Strategy and Increasing Population Size and An Iterative Local Search (NBIPOP-aCMAES). The verification criteria are based on how well the algorithm reaches convergence, memory usage, and statistical results. The results show that M-IFDO surpasses its competitors in several cases on the benchmark functions and five real-world problems.
