AI Insight
This paper introduces SCOPE, a framework that uses multiple AI agents to pursue and test scientific conjectures through equation modeling, experimentation, and evidence exchange, rather than simply optimizing individual equations. The researchers also present ClosureBench, a benchmark of 60 closure-discovery tasks across five scientific domains that evaluates not just equation accuracy but also the quality of evidence, mechanistic insights, and experimental efficiency. SCOPE demonstrates improved performance over existing methods in both discovering accurate equations and producing more reliable scientific conclusions.
Why it matters
This approach addresses a critical gap in automated scientific discovery by focusing on the testing and revision of scientific conjectures rather than mere curve-fitting. The framework could accelerate scientific research in fields requiring complex equation discovery, such as fluid dynamics and materials science, by automating the hypothesis-testing cycle and reducing reliance on human intuition alone.

Abstract: Most symbolic regression methods optimize candidate equations, but improving an equation’s fit does not establish whether its underlying scientific conjecture should be retained, revised, or rejected. A conjecture may admit multiple mathematical realizations, and similarly accurate equations may imply different explanations. This motivates a shift from refining individual expressions to developing and testing the conjectures that guide them. We introduce SCOPE, a framework that sustains multiple conjecture-driven research trajectories. Multiple scientist agents independently pursue conjectures through equation modeling, question formulation, and active experimentation, then exchange evidence to revise their conjectures and research directions. Their findings are consolidated into a scientific report linking models, conclusions, and evidence. Existing equation-discovery benchmarks primarily assess recovered expressions, leaving the evidence and scientific conclusions established through the investigation underexamined. We therefore introduce ClosureBench, an interactive benchmark of 60 closure-discovery tasks across five scientific domains. ClosureBench focuses on closure-discovery tasks to give equation discovery a concrete scientific purpose. Each task embeds an unknown algebraic relation in a known PDE system, where agents control experimental conditions in OpenFOAM to acquire new data for equation discovery. Beyond equation accuracy, ClosureBench proposes three metrics to evaluate the discovery process: evidence faithfulness, mechanism insight, and experimental effectiveness. Compared with diverse baselines, SCOPE achieves higher equation accuracy on both ClosureBench and a real-world scientific discovery case, while producing more accurate, reliable, and effective scientific discoveries.
