| Abstract: | This paper optimizes the steel truss structures by taking into account the fuzziness of constraints and employing GA and the fuzzy set theory.By comparing and analyzing the result,we can see the validity of the fuzzy GA.The advantages of the fuzzy GA include that it can increase likelihood of obtaining the global optimum solution,improve preciseness and reduce the number of iterations of convergence,and reduce total computer processing time. |
