The optimization is performed using a second layer of the same algorithm for a set of molecules of different sizes. Several sets of parameters were found that lead to a high performance of the algorithm in terms of the number of the minima found. The variation of the parameters for each molecule is discussed. A relationship between the changes of parameters as a function of the number of degrees of freedom of the molecule has been established.<\/jats:p>","DOI":"10.3233\/jcm-190026","type":"journal-article","created":{"date-parts":[[2019,5,31]],"date-time":"2019-05-31T11:45:10Z","timestamp":1559303110000},"page":"1127-1136","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Multi niche crowding genetic algorithm parameter tuning for molecular potential energy surface computation"],"prefix":"10.1177","volume":"19","author":[{"given":"B.","family":"El Merbouh","sequence":"first","affiliation":[{"name":"Universit\u00e9 Ibn Zohr","place":["Maroc"]}]},{"given":"A.","family":"El Gridani","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Ibn Zohr","place":["Maroc"]}]}],"member":"179","published-online":{"date-parts":[[2019,11]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cplett.2007.12.024"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp1117695"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcc.21478"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/ci9003305"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1142\/S0219633614500679"},{"issue":"3","key":"e_1_3_1_7_2","first-page":"145","article-title":"Polyalanine gas phase acidities determination and conformational space analysis by genetic algorithm assessment","volume":"2","author":"Bourjila B.","year":"2016","unstructured":"BourjilaB.
