A comparator-based constraint handling technique for evolutionary algorithms

Hikaru Takami et al.

Summary: This paper proposes a comparator-based constraint handling technique, MLVM, for solving constrained optimization problems in industrial design. The MLVM structure is simple and can be easily integrated into evolutionary algorithms. The method utilizes constraint weights and tolerances to improve optimization performance and preserve diverse solutions.

Simultaneous aircraft sizing and multi-objective optimization considering off-design mission performance during early design

Yu Cai et al.

Summary: Traditional aircraft conceptual design primarily focuses on determining top-level sizing parameters to meet specified performance constraints. However, commercial aircraft often require optimization for different objectives in actual missions. This paper addresses multi-objective design and multi-mission optimization problems in conceptual aircraft design using NSGA-II, revealing design differences and the impact of off-design mission weightings.
