# ctak-train

Self-play training loop for the ctak evaluators.

```sh
cd train
uv run nn-train --size 5 --iters 100 --games 200
```

Each iteration writes `../data/selfplay-<size>-v<iter>.json`, writes candidate
and champion weights to `../include/`, refits the candidate strengths over the
whole game history and redraws `../data/candidate_strength.png`.
