Wrong Proposals Could Delay the Search but Not Hide the Rule
Narcissus keeps LLM proposals as context-bearing syntax trees while leaving every grammar rule reachable.
Summary
Narcissus keeps LLM proposals as context-bearing syntax trees while leaving every grammar rule reachable.
Across five domains and two search backends, the synthesizer beat static guidance at every tested budget and consistently outperformed asking the model to repair its own proposal. It solved 40 percent of ARC tasks where raw proposals solved 13 percent and made no LLM call during search.
Why it matters
Narcissus keeps LLM proposals as context-bearing syntax trees while leaving every grammar rule reachable.
