Genetic algorithms in bidisciplinary (aerodynamics/electromagnetism) optimization


The genetic algorithm(GA) is a non-traditional, probability search and global optimization method similar to natural selection and evolution. The key points and control parameters of this method are briefly discussed. To apply it to a multiobjective and multidisciplinary optimization problem a kind of fitness function is suggested, in which the requirements of multiobjects and multiconstraints are considered and the nondimensional coefficients and panalty coefficients of the constraint function are also introduced. Numerical results of bidisciplinary optimization calculation show that the present method is effective, applicable, and robust.
