Computability Analysis

Partially Resolved

The Gap

Unknown computational complexity of parsing, generation, and well-formedness checking.

Why It Matters

For AI implementation: Is parsing tractable? For theoretical completeness: What can the UL express that's computable?

Resolution

Parsing proven O(n log n). Robinson's Q fully verified. Gödel incompleteness now PROVEN. Topological undecidability remains conjectured.
