en مدیریت عملیات Operations Managment پژوهشي Research this article proposes a new algorithm for finding a good approximate set of non-dominated solutions for solving generalized traveling salesman problem. Random gravitational emulation search algorithm (RGES<span dir="RTL"> (</span>is presented for solving traveling salesman problem. The algorithm based on random search concepts, and uses two parameters, speed and force of gravity in physics. The proposed algorithm is compared with genetic algorithm and experimental results show that the proposed algorithm has better performance and less runtime to be answered. gravitational emulation search, force of gravity, traveling salesman problem 103 112 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-1104-2&slc_lang=en&sid=1 Ahmad Sheibat Alhamdi andishesaaz@gmail.com 180031947532846005472 180031947532846005472 Yes correspond Alireza Hosseinzadeh Kashani hk.alireza@gmail.com 180031947532846005473 180031947532846005473 No Azad University of Tehran(North-Tehran)
