Ballad algorithm optimizes LLM use for heuristic discovery

A new bandit-based algorithm called Ballad has been developed to optimize the use of multiple Large Language Models (LLMs) in automated heuristic discovery. Researchers found that larger, more expensive LLMs do not consistently produce better results for NP-hard combinatorial optimization problems. Ballad adaptively selects and orchestrates a pool of LLMs, including frontier and open-weight models, to create an ensemble that can match or surpass individual model performance while significantly reducing costs.
