%A Grzywiński, Maksym %D 2020 %T Size and Shape Design Optimization of Truss Structures Using the Jaya Algorithm %K %X The metaheuristic algorithm is proposed to solve the weight minimization problem of truss structures, considering the shape and sizing design variables. Design variables are discrete and/or continuous. The design of truss structures is optimized by an efficient optimization algorithm called Jaya. The main feature of Jaya is that it does not require setting algorithm-specific parameters. The algorithm has a very simple formulation in which the basic idea is to approach the best solution and escape from the worst solution [6]. Analyses of structures are performed by a finite element code in MATLAB. The effectiveness of the Jaya algorithm is demonstrated using two benchmark examples: planar truss 18-bar and spatial truss 39-bar, and compared with results in references. %U https://cames.ippt.pan.pl/index.php/cames/article/view/282 %J Computer Assisted Methods in Engineering and Science %0 Journal Article %R 10.24423/cames.282 %P 177-184 %V 27 %N 2–3 %@ 2956-5839 %8 2020-05-27
