The results achieved using the EO in solving these problems are compared with those of recent algorithms. The computational results show that EO yields better outcomes and competitive results that can also be applied for the other problems studied.enLearning-based-optimizationMine blast algorithmStructural optimizationSearch algorithmTruss structuresOptimum designCrashworthiness optimizationEngineering optimizationDifferential evolutionHybrid approachRobot gripper mechanismPlanetary gearboxHydrostatic thrust bearingEquilibrium optimizer algorithmPhysical-based algorithmsScience & technologyTechnologyMaterials science, characterization & testingMaterials scienceArticle00067258290001055255963610.1515/mt-2020-00922195-8572
