The imperative need for the fuel-efficient design of vehicles with lightweight structures is also a soaring demand raised by the different industries. This research contributes to both areas by using both the hybrid Taguchi salp swarm algorithm-Nelder-Mead (HTSSA-NM) and the manta ray foraging optimization (MRFO) algorithm to optimize the structure and shape of the automobile brake pedal. The results of HTSSA-NM and MRFO are compared with some well-established metaheuristics such as horse herd optimization algorithm, black widow optimization algorithm, squirrel search algorithm, and Harris Hawks optimization algorithm to verify its performance. It is observed that HTSSA-NM is robust and superior in terms of optimizing shape with the least mass of the engineering structures. Also, HTSSA-NM realize the best value for the present problem compared to the rest of the optimizer.eninfo:eu-repo/semantics/closedAccessNature-inspired algorithmGradient-based optimizerHeat-transfer searchPerformanceHybrid salp swarm algorithmManta ray foraging optimizerNelder-meadStructural optimizationTaguchiWeight reductionScience & technologyTechnologyMaterials science, characterization & testingMaterials scienceArticle00079115980001070671364510.1515/mt-2022-00122195-8572
