Read the background

Harmonic reports that Aristotle generated machine-verified solutions for 2025 IMO Problems 1–5 from human-formalized problem statements, with the Lean proofs published.

Why it matters

The result shows a separate AI system producing five complete formal solutions to known high-level competition problems.

What counts as progress

Can an AI system find and machine-check solutions to five official IMO problems from manually formalized statements?
