“…Therefore, in this article, an effort was made to model the compressive strength of SCRC by adopting one of several machine learning methods. So far, metaheuristic methods, and especially neural networks, have been successfully applied in various fields, such as in the control and optimization of processes, economics, medicine, and engineering [ 6 , 7 , 8 , 9 , 10 ]. They have also been used to model the properties of concrete in fresh or solid state [ 11 , 12 , 13 , 14 , 15 ], but much less in concrete with the addition of rubber [ 16 , 17 , 18 ].…”
