## Notes

CodeLlama-13b fine-tuned (fill-in-the-middle, about 40 h on one RTX8000) on 574 Ludii games as the mutation operator in MAP-Elites over a PCA of 510-dimensional Ludii concept vectors (1,600 cells); fitness from compile and playability checks, random playouts, and MCTS self-play balance, decisiveness, completion, agency, coverage, and strategic depth.
