“…On the other hand, probabilistic optimization techniques, such as Evolutionary Algorithms (EA), are robust and present a better global behaviour than the MP methods when dealing with complex optimization problems [14,15]. EA are not vulnerable to being trapped in local optima and therefore can be considered as reliable in approaching the global optimum for non-convex constrained optimization problems.…”

“…Cascade optimization has been implemented using different deterministic optimizers [17], as well as using both deterministic and probabilistic optimizers [15,18]. The main advantage in combining different optimizers in a successive manner has to do with maximizing the exploitation of the advantages offered by various optimization algorithms and alleviating the influence of the corresponding disadvantages on the optimum design achieved.…”

“…On the other hand metaheuristics, due to their random search, are being considered more robust in terms of global convergence; they may suffer, however, from a slow rate of convergence towards the global optimum. When metaheuristics are adopted to perform the optimization, the solution of the finite element equations is of paramount importance since more than 95% of the total computing time is spent for the solution of the finite element equilibrium equations [1]. A second characteristic is that in place of a single design point metaheuristics work simultaneously with a population of design points in the space of design variables.…”

“…The effectiveness of evolutionary type algorithms in structural shape optimization has been examined in a number of cases. In shape optimization of truss structures [1], aerodynamic improvement [2,3] and shape optimization of 2D mechanical parts [4,5]. Evolutionary algorithms have also been applied in a number of sizing structural optimization problems [6][7][8].…”
