| Abstract: | The purpose of this paper is to present a hybrid genetic algorithm based on the genetic algorithm and the imitative full-stress method, according to the problems of topology optimization of truss structure with discrete variables. The approach adopted in the study is known as a co-evolution algorithm used to solve topology and size optimization of trusses. The results of examples indicate that the hybrid genetic algorithm is feasible and efficient. |
