Researchers have developed AILS-AHD, a novel approach that uses Large Language Models (LLMs) to automatically design and optimize heuristics for solving the Capacitated Vehicle Routing Problem (CVRP). This method integrates an evolutionary search framework with LLMs to dynamically generate ruin heuristics within the Adaptive Iterated Local Search (AILS) framework, and also employs an LLM-based mechanism for computational acceleration. Experiments show AILS-AHD outperforms state-of-the-art solvers, setting new best-known solutions for 8 out of 10 large-scale instances in the CVRPLib benchmark. AI
