| Abstract: | For the global shape optimization of truss structures, an improved simulated annealing is proposed, which enhances the accuracy, efficiency and versatility. The optimizations of continuous variables and discrete variables are combined by using the method of multi-objectives. And the results show that the algorithm enjoys high precision. |
