This paper presents a computational study of a nonlinear hepatitis C virus model that accounts for the influence of alcohol consumption on disease progression. We employ periodic neural networks, optimized using a hybrid genetic algorithm and the interior-point algorithm, to solve a system of six coupled nonlinear differential equations representing hepatitis C virus dynamics. This model has not previously been solved using the proposed technique, marking a novel approach. The proposed method\u2019s performance is evaluated by comparing the numerical solutions with those obtained from traditional numerical methods. Statistical measures such as mean absolute error, root mean square error, and Theil\u2019s inequality coefficient are used to assess the accuracy and reliability of the proposed approach. The weight vector distributions illustrate how the network adapts to capture the complex nonlinear behavior of the disease. A comparative analysis with established numerical methods is provided, where performance metrics are illustrated using a range of graphical tools, including box plots, histograms, and loss curves. The absolute error values, ranging approximately from 10\u22126 to 10\u221210, demonstrate the precision, convergence, and robustness of the proposed approach, highlighting its potential applicability to other nonlinear epidemiological models.<\/jats:p>","DOI":"10.3390\/computation13030066","type":"journal-article","created":{"date-parts":[[2025,3,6]],"date-time":"2025-03-06T06:02:13Z","timestamp":1741240933000},"page":"66","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Design of Periodic Neural Networks for Computational Investigations of Nonlinear Hepatitis C Virus Model Under Boozing"],"prefix":"10.3390","volume":"13","author":[{"given":"Abdul","family":"Mannan","sequence":"first","affiliation":[{"name":"Abdus Salam School of Mathematical Sciences, Government College University, Lahore 54600, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8642-0660","authenticated-orcid":false,"given":"Jamshaid","family":"Ul Rahman","sequence":"additional","affiliation":[{"name":"Abdus Salam School of Mathematical Sciences, Government College University, Lahore 54600, Pakistan"}]},{"given":"Quaid","family":"Iqbal","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Statistics, Binghamton University\u2014State University of New York, Binghamton, NY 13902, USA"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6263-7328","authenticated-orcid":false,"given":"Rubiqa","family":"Zulfiqar","sequence":"additional","affiliation":[{"name":"Abdus Salam School of Mathematical Sciences, Government College University, Lahore 54600, Pakistan"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"92","DOI":"10.4254\/wjh.v8.i2.92","article-title":"Chronic hepatitis C: This and the new era of treatment","volume":"8","author":"Bertino","year":"2016","journal-title":"World J.
