| Abstract: | A co evolution algorithm used to solve topology and size optimization of trusses is proposed. The mathematical models of topology and size optimization of trusses are given firstly, and then a co evolution mechanism for optimization of both models, including coding strategies and the construction of fitness functions, is described. To demonstrate the performance of the algorithm, an example of ten bar truss optimization with discrete cross section areas is presented. |
