Limits RegistryPUBLIC RECORD
Limits RegistryGoogle DeepMind's AlphaDev used deep reinforcement learning to discover assembly-level sorting routines for short sequences (3-5 elements) that were up to 70% faster than the existing LLVM libc++ implementations, and about 1.7% faster for sequences over 250,000 elements. Published in Nature in June 2023, the routines were merged into libc++, the first change to that sorting code in over a decade.

The maximum reported speed improvement of AI-discovered sorting routines merged into the LLVM libc++ standard library.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
