Simultaneous sizing, shape, and layout optimization and automatic member grouping of dome structures
TLDR
To obtain an automatic member grouping of the bars of the trusses analyzed in this paper, a specific encoding using cardinality constraints is considered and trade-off curves are provided, showing the optimized weights in comparison with the number of distinct cross-sectional areas used in the solutions.About:
