Chemically-Validated Reasoning
RePO generates chemically sound and interpretable reasoning trajectories, correctly identifying structural elements and proposing valid modifications, unlike baselines prone to errors.
MR Optimization Example
Problem: Modify the molecule Cc1ccc(NC(=O)C(C)(C)C(=O)N2CCCC2)cc1Br to have a lower MR.
GRPO: Misinterprets "MR", proposes chemically implausible modifications.
RePO: Correctly interprets MTR, identifies key features (bromine, carbonyl, nitrogen), and proposes substituting bromine with chlorine.
