TL;DR: The effectiveness of the FA at solving this type of optimisation problem is demonstrated with benchmark problems, the results for which are better than those reported in the literature and obtained with lower computational costs, emphasising the capabilities of the proposed methodology.

TL;DR: The Search Group Algorithm (SGA) is successfully applied for the structural optimization of trusses and found the lightest structures available in the literature, to the best of the authors' knowledge.

TL;DR: A comparison of the performance (computational cost) of the main strategies of RBDO strategies is presented for several variants of two benchmark problems from the literature and for a structure modeled using the finite element method.

TL;DR: In this paper, the authors analyse how different the optimal structures are when different first-ply failure criterion are considered in the optimization of laminated composites and show that optimal structures highly differ when different failure criteria are considered and that none of the failure criteria is always the most or the least conservative when different load conditions are applied.

TL;DR: In this paper, the robust optimization of TMD and MTMD is applied to vehicle-bridge coupled vibration problems, where parameters of the TMD, of pavement irregularity models and of the bridge-vehicle models are considered as random variables.
