Summary

Higher-order production rules captured rings while remaining compatible with ordinary sequence models.

Higher-order Grammar Representation lifts molecules into combinatorial complexes and serializes them as context-free production rules. On the new ring-enriched RingDiv benchmark and five generation tests, the authors report 100 percent validity by construction and leading distributional alignment; its foundation model also led mean AUC across seven MoleculeNet benchmarks under probing and full fine-tuning. The representation's advantage is benchmarked against the selected baselines and does not itself establish chemical usefulness or synthesizability.

Why it matters

Higher-order production rules captured rings while remaining compatible with ordinary sequence models.
