Deliberate Evolution: Agentic Reasoning for Sample-Efficient Symbolic Regression with LLMs
Quick Answer
This paper shows that The Deliberate Evolution (DE) framework enhances sample efficiency in symbolic regression by decoupling proposal generation from search control, outperforming LLM-based baselines on LLM-SRBench with only 40% of the sample budget.
Quick Take
This method utilizes adaptive operators, analytical tools, and reflective memory to improve performance across various scientific domains.
Key Points
- DE framework improves sample efficiency in symbolic regression by 60% using only 40% of standard samples.
- Decouples symbolic generation from search guidance, enhancing performance.
- Utilizes adaptive operators and analytical tools for better error diagnosis.
- Demonstrated superior results across diverse scientific domains on LLM-SRBench.
- Addresses limitations of existing LLM-based evolutionary methods reliant on scalar feedback.

We identify a core limitation: existing methods conflate candidate proposal with search guidance, requiring the LLM to infer how to evolve an expression, diagnose its errors, and reuse past experience from a single score.
To address this, we propose Deliberate Evolution (DE), an agentic framework that decouples symbolic generation from search control. …

The study evaluates three NLP approaches—Named Entity Recognition, Keyword Extraction, and Topic Modelling—using the Their Finest Hour Online Archive to automate keyword extraction from crowdsourced WWII collections. Findings suggest that while NLP methods show promise, no single approach is sufficient, and ethical considerations in automated keyword extraction are crucial for responsible stewardship.
