  • Other Evolutionary algorithms (EAs) have been widely used in design optimization that often requires expensive evaluations (e.g., computational fluid dynamics: CFD). An artificial neural network (ANN) based surrogate model is used in the EA optimization routines to reduce the time for these expensive evaluations. The ANN can model the relationship between many design variables and objective functions in a single surrogate model, unlike other surrogate models (e.g., Kriging). In this study, a genetic algorithm (GA) coupled with a dynamically retrained ANN is proposed and applied to multi-objective transonic airfoil shape optimization where aerodynamic performances are evaluated with CFD. The proposed method is shown to converge more quickly towards the Pareto-optimal front with fewer CFD evaluations compared to a stand-alone GA, proving the efficacy of ANN as the surrogate model in the GA.
