With the development of theory and computing technology,simulations with high-fidelity model are available.However,when it comes to finite element analysis (FEA) and computational fluid mechanicals (CFD),in which a single simulation may cost several hours,the time cost of the global optimization is unbearable.Moreover,the traditional gradient-based optimization algorithm,such as sequential quadratic programing (SQP) is fast but may lose the global optimum,while the global algorithm,such as genetic algorithm (GA),is too expensive,due to the thousands of high-fidelity model evaluations.
