Polyfish

An AI model and Rust game simulator based on the Polytopia strategy game.

I built the original version in TS then worked with AI to translate it to Rust.

Quick Start

1. Install Rust
2. Run ./run-server.sh
3. Go to http://localhost:3000

Training

• polyfish-rs/local_setup.sh: Install Python requirements.
• polyfish-rs/run_training_loop.sh: Launch the training loop.

Game

• polyfish-rs/: Exact (i hope) replica of the Polytopia game logic with an AI/MCTS agent.
• src/public/: Web UI for playing with the simulator and AI.
• run-server.sh: Helper script to launch the backend server UI to play the simulated game.
• notes.md: Research and architecture info.

AI

• polyfish-rs/src/ai/mcts_zero.rs: Alpha-Zero style MCTS.
• polyfish-rs/src/ai/network.rs: Neural network architecture.
• polyfish-rs/src/ai/features.rs: Gamestate feature extraction.
• polyfish-rs/src/ai/heuristics.rs: Economy and Military based heuristic evaluation.
• polyfish-rs/src/ai/evaluation.rs: Winning position evaluation function.
• polyfish-rs/src/ai/opening.rs: Standard opening moves book for different tribes.

GameState Ripper

• polyfish-reader/polyai-reader: C++ script that injects into the running Steam game and extracts the real game state. Ready to be parsed by the Rust simulator.
• polyfish-reader/inputer: Failed attempt to manipulate the game's live state into playing AI moves.
