In this paper, the authors carried out the optimization of an isogrid structure considering six different responses: Tsai-Wu failure index under compression and torsion efforts; instability coefficient under compression and torsion efforts; mass and natural frequency. The response surface methodology was used to find the functions that describe the model from the data found by numerical analysis; and a new optimization algorithm called SunFlower Optimization (SFO) was used to find the best possible configurations. This paper shows something unprecedented in the literature to date when evaluating the compression, torsion, and modal performance of an isogrid tube. The simultaneous evaluation of several responses brings something more real to the scientific world, the results obtained here suggest that the optimal configuration for one response can be very bad for others and the use of a multi-objective optimization solved this problem.

在本文中，作者考虑了六个不同的响应来进行了等距结构的优化：压缩和扭转作用下的Tsai-Wu破坏指标；压缩和扭转作用下的不稳定性系数；质量和自然频率。响应面方法用于从数值分析发现的数据中找到描述模型的功能。然后使用一种称为SunFlower Optimization（SFO）的新优化算法来找到最佳配置。当评估等斜管的压缩，扭转和模态性能时，本文显示了迄今为止文献中前所未有的内容。同时评估多个响应给科学界带来了更真实的东西，
