IS-Jaya is the enhanced version of the Jaya algorithm that the shuffling process and escaping from local optima are added for it. These two modifications increase the population diversity and ability the escape from the local optima of the Jaya. The robustness and performance of the IS-Jaya are evaluated by the three design examples. The results show that the IS-Jaya algorithm outperforms other state-of-the-art optimization techniques considered in the literature.</span></span></h3> improved shuffled based Jaya algorithm, metaheuristic, structural optimization, braced dome structures, frequency constraints. 609 625 http://ijoce.iust.ac.ir/browse.php?a_code=A-10-66-358&slc_lang=en&sid=1 A.
