Firstly, circle chaotic mapping is used to increase the diversity of the population. Secondly, a math optimizer accelerated (MOA) function optimized by means of a composite cycloid is proposed to improve the convergence speed of the algorithm. Meanwhile, the symmetry of the composite cycloid is used to balance the global search ability in the early and late iterations. Thirdly, an optimal mutation strategy combining the sparrow elite mutation approach and Cauchy disturbances is used to increase the ability of individuals to jump out of the local optimal. The Rastrigin function is selected as the reference test function to analyze the effectiveness of the improved strategy. Twenty benchmark test functions, algorithm time complexity, the Wilcoxon rank-sum test, and the CEC2019 test set are selected to test the overall performance of the improved algorithm, and the results are then compared with those of other algorithms. The test results show that the improved algorithm has obvious advantages in terms of both its global search ability and convergence speed. Finally, the improved algorithm is applied to an engineering example to further verify its practicability.<\/jats:p>","DOI":"10.3390\/sym14051011","type":"journal-article","created":{"date-parts":[[2022,5,16]],"date-time":"2022-05-16T21:36:06Z","timestamp":1652736966000},"page":"1011","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["A Multi-Strategy Improved Arithmetic Optimization Algorithm"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5983-7070","authenticated-orcid":false,"given":"Zhilei","family":"Liu","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering and Automation, Dalian Polytechnic University, Dalian 116034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingying","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Dalian Polytechnic University, Dalian 116034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guibing","family":"Pang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Dalian Polytechnic University, Dalian 116034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongxiang","family":"Song","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Dalian Polytechnic University, Dalian 116034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Dalian Polytechnic University, Dalian 116034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0680-6916","authenticated-orcid":false,"given":"Hui","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Dalian Polytechnic University, Dalian 116034, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3442","DOI":"10.1177\/0954406215612831","article-title":"Optimal dynamic design of planar mechanisms using teaching learning based optimization algorithm","volume":"230","author":"Chaudhary","year":"2016","journal-title":"Proc.
