Wolf pack algorithm is a technique often used for computing the global optimum of a multivariable function. In this paper, we develop a new wolf pack algorithm that can accurately compute the optimal value of a high\u2010dimensional function. First, chaotic opposite initialization is designed to improve the quality of initial solution. Second, the disturbance factor is added in the scouting process to enhance the searching ability of wolves, and an adaptive step length is designed to enhance the global searching ability to prevent wolves from falling into the local optimum effectively. A set of standard test functions are selected to test the performance of the proposed algorithm, and the test results are compared with other algorithms. The high\u2010dimensional and ultrahigh\u2010dimensional functions (500 and 1000) are tested. The experimental results show that the proposed algorithm features in good global convergence, high accuracy calculation, strong robustness, and excellent performance in high\u2010dimensional functions.<\/jats:p>","DOI":"10.1155\/2021\/6676934","type":"journal-article","created":{"date-parts":[[2021,2,14]],"date-time":"2021-02-14T04:44:47Z","timestamp":1613277887000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Chaotic Disturbance Wolf Pack Algorithm for Solving Ultrahigh\u2010Dimensional Complex Functions"],"prefix":"10.1155","volume":"2021","author":[{"given":"Qiming","family":"Zhu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0692-7467","authenticated-orcid":false,"given":"Husheng","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Na","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinqiang","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,2,12]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/7237459"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.17775\/cseejpes.2018.01010"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1088\/1755-1315\/108\/5\/052075"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/1038908"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/9462158"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/5876318"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00521-019-04255-0"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00500-016-2081-6"},{"key":"e_1_2_9_9_2","first-page":"72","article-title":"Modified dolphin swarm algorithm based on chaotic maps for solving high-dimensional function optimization problems","volume":"7","author":"Weibiao Q.","year":"2019","journal-title":"IEEE Access"},{"key":"e_1_2_9_10_2","first-page":"2430","article-title":"New swarm intellingence algorithm\u2014wolf pack algorithm","volume":"35","author":"Wu H.
