This paper proposes an improved sparrow search algorithm based on iterative local search (ISSA). In the global search phase of the followers, the variable helix factor is introduced, which makes full use of the individual\u2019s opposite solution about the origin, reduces the number of individuals beyond the boundary, and ensures the algorithm has a detailed and flexible search ability. In the local search phase of the followers, an improved iterative local search strategy is adopted to increase the search accuracy and prevent the omission of the optimal solution. By adding the dimension by dimension lens learning strategy to scouters, the search range is more flexible and helps jump out of the local optimal solution by changing the focusing ability of the lens and the dynamic boundary of each dimension. Finally, the boundary control is improved to effectively utilize the individuals beyond the boundary while retaining the randomness of the individuals. The ISSA is compared with PSO, SCA, GWO, WOA, MWOA, SSA, BSSA, CSSA, and LSSA on 23 basic functions to verify the optimization performance of the algorithm. In addition, in order to further verify the optimization performance of the algorithm when the optimal solution is not 0, the above algorithms are compared in CEC 2017 test function. The simulation results show that the ISSA has good universality. Finally, this paper applies ISSA to PID parameter tuning and robot path planning, and the results show that the algorithm has good practicability and effect.<\/jats:p>","DOI":"10.1155\/2021\/6860503","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T23:05:36Z","timestamp":1639609536000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Improved Sparrow Search Algorithm Based on Iterative Local Search"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4076-4641","authenticated-orcid":false,"given":"Shaoqiang","family":"Yan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5761-7031","authenticated-orcid":false,"given":"Ping","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9868-8103","authenticated-orcid":false,"given":"Donglin","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1628-4090","authenticated-orcid":false,"given":"Wanli","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5393-3475","authenticated-orcid":false,"given":"Fengxuan","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2019.2948596"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCYB.2019.2939219"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/tcyb.2021.3086181"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCYB.2020.3025662"},{"key":"e_1_2_12_5_2","doi-asserted-by":"crossref","unstructured":"YangX.-S.
