<p>Quasi-Newton algorithms, particularly the BFGS technique, are well-defined methods for solving unconstrained single-objective optimization problems that have recently been extended to multiobjective optimization. However, implementing these methods for large-scale problems proves challenging due to the need to store Hessian approximations. To address this challenge, we suggest a scaled memoryless BFGS quasi-Newton technique designed for large-scale multiobjective optimization problems (MOPs), which eliminates the requirement for matrix storage while preserving convergence properties. Our approach applies a novel scaling technique to enhance efficiency and approximates the Pareto front uniformly through an iterative, memory-efficient approach. To validate the procedure, we investigate numerical test problems using well-known performance metrics and compare the results with some existing algorithms. The findings show that the suggested approach attains superior computational efficiency and solution quality, specially in high-dimensional settings. This study bridges the deep gap in large-scale multiobjective optimization, by suggesting a scalable and practical alternative to standard quasi-Newton techniques while maintaining theoretical rigor.</p>
