# IOAI 2026 — Find the Order

Official contest data for **Find the Order**, task 1 (Day 1) of the [IOAI 2026](https://ioai-official.org) Individual Contest, held in Astana, Kazakhstan.

Spoken English dialogues are segmented into speaker turns, one `.wav` per turn, and shuffled. Contestants reconstruct the original turn order. `prefix.json` in each dialogue folder gives the first two chunk indexes, fixing the reading direction.

The task statement, translations, baseline and grader live in the [IOAI-2026 GitHub repository](https://github.com/IOAI-official/IOAI-2026/tree/main/Individual-Contest/1_Find_the_Order). This repository holds **data only**.

## Subsets

| Subset | Path | Contestants saw it | Role |
|---|---|---|---|
| Public – train | `public/train/` + `public/train_answers.json` | yes | labelled dialogues |
| Public – dry-run | `public/pretrain/`, `public/pretest/` + answers | yes | 20-dialogue slices for pipeline validation |
| Private – Leaderboard A | `private/test_leaderboard_a/` + `private/test_leaderboard_a_answers.json` | no | **live leaderboard** during the contest |
| Private – Leaderboard B | `private/test_leaderboard_b/` + `private/test_leaderboard_b_answers.json` | no | **final ranking** |

Audio: mono, 44.1 kHz; 7–20 chunks per dialogue. Answers files sit at the subset root, matching the contest grader's layout.
