| Abstract: | Combined with GA（genetic algorithm）, BP neural network is introduced into the optimization design of beam string structures and the imitated full-stress method for structures with discrete variables is amended to form a new type of combinational optimization method. Furthermore, the new method is applied into the BSS computational example, and results verify the validity and reliability of the algorithm with fast calculation speed. |
