Legacy research stacks

The supported project path is the JAX rules engine and JAX PPO tooling exposed by lost-cities-jax-ppo. The historical Deep CFR and ISMCTS implementations are preserved for research reproduction, but they are not current training recipes and no longer have public console-script entry points.

What is preserved

  • Deep CFR sources: src/coolrl_lost_cities/games/classic/deep_cfr/
  • ISMCTS sources: src/coolrl_lost_cities/games/classic/ismcts/
  • Their retired configurations: legacy/deep-cfr/configs/ and legacy/ismcts/configs/
  • Earlier plans and dated findings: docs/plans/archive/, docs/archive/, and docs/research/

These files remain in the repository so a historical experiment can be read or reproduced against its original commit. They should not be chosen for new models, benchmarks, or product work.

Current workflow

Start from configs/jax_ppo/, run lost-cities-jax-ppo, and use the browser client in web/. The root README contains the short training, evaluation, and static-web recipes.
