Abstract: Optimization problems are fundamental across various fields, including logistics, machine learning, and bioinformatics, where challenges are often characterized by complexity, high dimensionality. Modeling the interplay among multiple objectives is beneficial for optimization. However, existing Neural Combinatorial Optimization (NCO) methods and Large Language Model (LLM)-based approaches show limitations in adaptability and computational efficiency, primarily focusing on single-objective optimization. In this paper, we propose a novel framework, Multi-Objective Hierarchical Reflective Evolution (MHRE), for optimizing and generating heuristics algorithms for a broad range of optimization problems. Specifically, we extend the optimization space of the conventional hyper-heuristic methodologies, which allows us to unify similarity algorithms. We successfully construct Generalized Evolutionary Metaheuristic Algorithm (GEMA) for unifying metaheuristic algorithms. Yielding improved performance in experimental results. To show the performance of our method, we further applied the MHRE framework to optimize the Ant Colony Optimization (ACO) algorithm, achieving state-of-the-art results on random TSP problems and the TSPLib benchmark datasets. Our findings illustrate that the MLHH framework offers a robust and innovative solution for tackling complex optimization challenges, paving the way for future research in this area.
