Jaya algorithm (JA) is a single-phase metaheuristic algorithm using best and worst existing solutions. The effects of these solutions are equally considered in the classical form. In the proposed modified algorithm, a weight factor is considered for these factors. This factor is randomly chosen to keep the algorithm as a parameter-free one. The results of modified JA (MJA) and JA are compared and evaluated for optimization of carbon fiber-polymers (CFRP) used for increasing the shear force capacity of reinforced concrete beams. The results show that MJA outperforms JA. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.eninfo:eu-repo/semantics/closedAccessCFRP; Jaya algorithm; Modified jaya algorithm; Optimization; Reinforced concrete; Shear forceBook Chapter54725125610.1007/978-3-031-65976-8_132-s2.0-85201933773Q4
