The EChOA integrates a self-adaptive DE\/current-to-pbest\/1 (with jDE-style parameter control) variation stage with the canonical four-leader ChOA guidance and augments the search with three lightweight modules: (i) L\u2019evy flight refinement around the incumbent best, (ii) periodic elite opposition-based learning, and (iii) stagnation-aware partial restarts. The EChOA is compared with more than 35 optimizers on the CEC2022 single-objective suite (12 functions). The results shows that the EChOA attains state-of-the-art results at both D=10 and D=20. At D=10, it ranks first on all functions (average rank 1.00; 12\/12 wins) with the lowest mean objective and the smallest dispersion relative to the strongest competitor (OMA). At D=20, the EChOA retains the best overall rank and achieves top scores on most functions, indicating stable scalability with problem dimension. Pairwise Wilcoxon signed-rank tests (\u03b1=0.05) against the full competitor set corroborate statistical superiority on the majority of functions at both dimensions, aligning with the aggregate rank outcomes. Population size studies indicate that larger populations primarily enhance reliability and time to improvement while yielding similar terminal accuracy under a fixed iteration budget. Four constrained engineering case studies (including welded beam, helical spring, pressure vessel, and cantilever stepped beam) further confirm practical effectiveness, with consistently low cost\/weight\/volume and tight dispersion.<\/jats:p>","DOI":"10.3390\/computation14010001","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T07:01:33Z","timestamp":1766386893000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhanced Chimp Algorithm and Its Application in Optimizing Real-World Data and Engineering Design Problems"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9170-3291","authenticated-orcid":false,"given":"Hussam N.","family":"Fakhouri","sequence":"first","affiliation":[{"name":"Faculty of Artificial Intelligence, Al-Balqa Applied University, Al-Salt 19117, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riyad","family":"Alrousan","sequence":"additional","affiliation":[{"name":"Design and Visual Communication Department, School of Architecture and Built Environment (SABE), German Jordanian University (GJU), Madaba 11180, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6786-8395","authenticated-orcid":false,"given":"Hasan","family":"Rashaideh","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Al-Balqa Applied University; Al-Salt 19117, Jordan"},{"name":"Faculty of Information Technology, Aqaba University of Technology, Aqaba 77110, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7548-0529","authenticated-orcid":false,"given":"Faten","family":"Hamad","sequence":"additional","affiliation":[{"name":"Information Studies Department, Sultan Qaboos University, Muscat 123, Oman"},{"name":"Information Sciences and Educational Technology Department, School of Educational Sciences, The University of Jordan, Amman 11196, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2013-6923","authenticated-orcid":false,"given":"Zaid","family":"Khrisat","sequence":"additional","affiliation":[{"name":"Faculty of Arts and Educational Sciences, Middle East University, Amman 11831, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,20]]},"container-title":["Computation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mdpi.com\/2079-3197\/14\/1\/1\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T07:22:36Z","timestamp":1766388156000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.mdpi.com\/2079-3197\/14\/1\/1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,20]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1]]}},"alternative-id":["computation14010001"],"URL":"https:\/\/doi.org\/10.3390\/computation14010001","relation":{},"ISSN":["2079-3197"],"issn-type":[{"value":"2079-3197","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,20]]}}}
