The article discusses research investigating the symmetry and asymmetry of optimal solutions in symmetric structural optimization problems, based on several variables. Researchers' used a group theory approach to define the symmetry of the structural problems, noting that the approach allows the set of symmetric structures to be described and related to the entire search space of the problem. An overview of discrete variable optimization in structural engineering is presented.
