A Human-on-the-Loop Optimization Autoformalism Approach for Sustainability
CoRR, 2023 This paper outlines a natural conversational approach to solving personalized energy-related problems using large language models (LLMs). We focus on customizable optimization problems that necessitate repeated solving with slight variations in modeling and are user-specific, hence posing a challenge to devising a one-size-fits-all model.
