# ICS datasets

The Light-Up, Nurikabe, Tapa and Heyawake datasets of ICS (code: https://github.com/icsearch/ICS). Each folder holds a
`test` and a `train` split in the layout the code reads:

| Folder | Puzzle | Test boards (random + golden) | Train boards | Train rows |
|---|---|---|---|---|
| `lightup-ms26` | Light-Up | 113 (100 + 13) | 1,431 | 11,448 |
| `ppb-nurikabe-ms26` | Nurikabe | 115 (100 + 15) | 2,282 | 22,820 |
| `ppb-tapa-ms26` | Tapa | 65 (50 + 15) | 580 | 5,800 |
| `ppb-heyawake-ms26` | Heyawake | 115 (100 + 15) | 5,564 | 55,640 |

## Loading

```python
from huggingface_hub import snapshot_download

root = snapshot_download(repo_id="hcshi/ICS-data", repo_type="dataset", allow_patterns="ppb-tapa-ms26/*")
```

With the code installed, `python -m ics download --dataset --task tapa` writes the same folder to `data/tapa`. Pass
a folder, e.g. `<root>/ppb-tapa-ms26`, as `--data` to `python -m ics train` or `python -m ics eval`.
