【Abstract】 A genetic algorithm suitable for using in structure design optimization with discrete variables is developed. The genetic scheme representing the structure design problem with discrete variables is presented, and a sub space constructing method for reducing the genetic search region is proposed. The algorithm developed can be used to deal with structure optimization problems with stress and displacement constraints. A numerical example shows that it is of high efficiency and good adaptability.更多还原
