New FrugalEvo framework optimizes LLM-guided program evolution by cost

Researchers have introduced FrugalEvo, a novel framework designed to optimize program evolution by considering computational costs. This approach utilizes a stronger, more expensive LLM to devise strategies and a cheaper LLM to implement and refine the resulting code. FrugalEvo aims to maximize performance gains within a fixed budget, introducing a Budget-Aware Area Under the Curve (BA-AUC) metric to measure quality over cost. In evaluations across mathematical, systems, and algorithmic optimization tasks, FrugalEvo matched or surpassed existing state-of-the-art methods, notably achieving new state-of-the-art results in circle packing with significantly reduced costs compared to multi-agent systems.
