Researchers have developed a new framework called Stackelberg Program Optimization (SPO) to discover effective destroy and repair operators for large neighborhood search (LNS) algorithms. SPO utilizes an LLM-based approach to create adaptive programs that condition operator decisions on the evolving LNS state. This method organizes the discovery process as a Stackelberg interaction, where destroy operators act as leaders and repair operators as conditional followers, guiding a combined LLM learning and evolutionary search. Experiments on the traveling salesperson problem and capacitated vehicle routing problem demonstrated that SPO surpasses existing strong baselines and generalizes to larger problem instances. AI
