Conditional

The standing rule says every unsolved problem automatically reopens for the next year with the same rules and an award equal to that year in euros. The live intake page is stale at €2,023 and a January 2024 deadline, so the €2,026 value is formula-derived and current submission terms must be confirmed with KCIK.

Nominally active under the automatic-renewal clause; 2026 intake details are unconfirmed.
