IMO 2025 Problems Dataset

This dataset contains the 6 problems from the 2025 International Mathematical Olympiad (IMO). The problems are formatted with proper LaTeX notation for mathematical expressions.

Dataset Structure

Each example contains:

• id: Problem identifier (e.g., "2025-imo-p1")
• problem: The problem statement with LaTeX mathematical notation
• solution: The solution (currently set to null)

Problem Types

The dataset includes problems covering various mathematical areas:

1. Problem 1: Combinatorial geometry (sunny lines)
2. Problem 2: Euclidean geometry (circles and triangles)
3. Problem 3: Number theory (bonza functions)
4. Problem 4: Number theory (proper divisors and sequences)
5. Problem 5: Game theory (inekoalaty game)
6. Problem 6: Combinatorial geometry (grid tiling)

Mathematical Notation

Mathematical expressions are formatted using LaTeX:

• Variables and expressions: $x$, $n \geq 3$
• Display equations: $$f(a) \text{ divides } b^a - f(b)^{f(a)}$$
• Sets: $\mathbb{N}$, $\mathbb{R}$
• Special formatting: sunny, bonza, proper divisor, inekoalaty game

Files

• imo_2025.json: Full dataset in JSON format
• README.md: This file

Usage

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("lmms-lab/imo-2025")

# Access individual problems
for problem in dataset['train']:
    print(f"Problem: {problem['id']}")
    print(f"Statement: {problem['problem']}")
    print()

Or load directly from JSON:

import json

# Load from JSON
with open("imo_2025.json", "r") as f:
    problems = json.load(f)

# Access problems
for problem in problems:
    print(f"ID: {problem['id']}")
    print(f"Problem: {problem['problem']}")
    print(f"Solution: {problem['solution']}")
    print()
