Hybrid Optimization Method Based on the Best Vertex and Its Application to Optimization Design of Airfoil
摘要
Abstract
In order to improve the computational efficiency of genetic algorithm (GA) and avoid getting a local optimum solution in complex method (CM), these two methods were combined together using their advantages to form a hybrid optimization method based on the best vertex (GA&CM) in this investigation. In this method, GA was used to get an approximate global optimum solution in design space. Then this solution was taken as the initial vertex of CM to search for a final solution. GA, CM and the hybrid method have been used in the aerodynamic optimization design of RAE2822 airfoil. The results show that the hybrid method is more efficient and can converge to global optimum solution better.关键词
