The application of asexual dna algorithm to airfoil design

With the development of genetic engineering, many kinds of algorithms based on it have been applied to engineering design fields. Among those, Genetic algorithms are based on Darwin's Naturalistic evolutionism of which the main idea is natural selection and survival of the fittest, and Genetic algorithms simulate the evolutionary mechanism of sexual reproduction. Since Genetic algorithms have global convergence and wide feasibility, they have been applied maturely to aerodynamic design. Whereas, in the practical use of Genetic algorithms, there are problems such as they are incapable of representing the bidirectional evolution and the effects of mutation and crossover are not equal. In order to solve the problems, in this paper, an Asexual DNA (Deoxyribonucleic Acid) algorithm, which simulates the evolutionary mechanism of asexual reproduction, is applied to airfoil design. Compared with Genetic algorithms, Asexual DNA algorithm has faster global convergence and better optimal effect.
