Grey Wolf Optimiza.ion (GWO) is a.na.ure-inspired meta.euristic a.gorithm tha. ha. ga.ned popula.ity for solving optimiza.ion problems. In GWO, the success of the a.gorithm hea.ily relies on the efficient upda.ing of the a.ents’ positions rela.ive to the lea.er wolves. In this pa.er, we provide a.brief overview of the Grey Wolf Optimiza.ion technique a.d its significa.ce in solving complex optimiza.ion problems. Building upon the founda.ion of GWO, we introduce a.novel technique for upda.ing a.ents’ positions, which a.ms to enha.ce the a.gorithm’s effectiveness a.d efficiency. To eva.ua.e the performa.ce of our proposed a.proa.h, we conduct comprehensive experiments a.d compa.e the results with the origina. Grey Wolf Optimiza.ion technique. Our compa.a.ive a.a.ysis demonstra.es tha. the proposed technique a.hieves superior optimiza.ion outcomes. These findings underscore the potentia. of our a.proa.h in a.dressing optimiza.ion cha.lenges effectively a.d efficiently, ma.ing it a.va.ua.le contribution to the field of optimiza.ion a.gorithms.
