Equational Theories Selected Problems
Update (September 11, 2026)
This dataset was updated on September 11, 2026.
Main changes:
released the official Stage 2 evaluation problems: stage2_evaluation_main (200 problems; ground truth withheld — answer is null until Stage 2 concludes) and stage2_evaluation_research (100 order-5 research problems with no ground truth)
added metadata/stage2_evaluation_main.json and metadata/stage2_evaluation_research.json… See the full description on the dataset page: https://huggingface.co/datasets/SAIRfoundation/equational-theories-selected-problems.problematic-mo-eval-datacountdown_problemsIMO-2026-Problems
IMO 2026 Problems
The six IMO 2026 problem statements, indexed from 0 through 5 in contest order.
IDs 0–2 are from Day 1, and IDs 3–5 are from Day 2.
Schema
id: zero-based problem identifier (0 corresponds to Problem 1).
day: contest day (1 or 2).
problem: complete English problem statement.
