# 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

```python
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:

```python
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()
```
