NOM embeds the trained neural surrogate as the objective function,achieving end-to-end differentiable optimization. This yields high accuracy with reduced computation time (up to 20-25% fasterthan Genetic Algorithm). NOM’s performance is tested comprehensively on test functions (such as McCormick, Rosenbrock,and Mishra’s Bird). The framework is validated with computational experiments through optimization of a re-entrant auxeticmetamaterial structure design, achieving an optimal negative Poisson’s Ratio, ν = -1.55, showcasing NOM’s direct applicability toengineering structures, viz. a monolithic smart morphing wing. The results highlight NOM’s versatility and scalability, paving theway for broader applications in topology optimization, aerodynamic design, and material science.
