15 Puzzle
This repository contains SFT, RL, and evaluation data for the 15-puzzle task.
Files
data/sft-00000-of-00001.parquet: 600 supervised fine-tuning puzzlesdata/eval-00000-of-00001.parquet: 100 held-out evaluation puzzlesdata/rl-00000-of-00001.parquet: 10,000 reinforcement learning puzzles
SFT data
The SFT split contains 600 puzzles across scramble depths 8 through 15, with
75 puzzles at each depth. Each puzzle was solved with an optimal solver, and
the resulting move trajectory was annotated with concise rationales generated
by deepseek-v4-flash.
The examples contain prompt/completion trajectories in chat format, along with metadata such as:
idboardscramble_depthoptimal_movesoptimal_lengthmove_countsplit
Evaluation data
The unchanged eval split contains 100 held-out puzzles with:
boardscramble_depthbucketsplitoptimal_movesoptimal_length
RL data
The RL split contains 10,000 unique puzzles that do not overlap with the SFT or evaluation splits:
- 146 trivial puzzles at optimal lengths 1 through 6
- 2,854 easy puzzles at optimal lengths 7 through 12
- 4,000 medium puzzles at optimal lengths 13 through 24
- 3,000 hard puzzles at optimal lengths 25 through 80
Each row contains:
idboardbucketsplitscramble_depthoptimal_movesoptimal_length
Notes
Moves are defined as the numbered tile moving into the blank, not the blank moving.
