| Abstract: | According to the characteristics of structural optimal design problems based on reliability, a genetic algorithm is introduced. The selection of the parameters and its effect on convergence are discussed. Two structural optimal design problems based on reliability are taken as examples to verify the effectiveness of the genetic algorithm. |
