| Abstract: | In this paper,an Hybrid Genetic Algorithms(HGA) which combined with Forward-and-Back Searching Algorithms(FBSA) was proposed for the defects of the Genetic Algorithms(GA),and a model of structural optimization with discrete variables was derived.A truss structure with 11 bars is optimized as well.Calculation results show the Hybrid Genetic Algorithms is fast in convergence and high in accuracy,which will be effective in optimization design of discrete variable. |
