Query‐Based Preference Optimization for Aircraft Design: A Comparative Study of Utility‐Driven and Human‐in‐the‐Loop Approaches

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
In aircraft multiobjective design optimization, conventional approaches typically adopt a posteriori methodology, requiring complete generation of nondominated solutions before subsequent selection. This process inevitably incurs substantial computational overhead through exploration of noncritical design spaces. To overcome this limitation, we propose
