| 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. |
