AEI

AEI Readme

This package provides a specification for the Arimaa Engine Interface (AEI). It also includes some tools for using engines that implement AEI. Including an interface to the arimaa.com gameroom. A full description of AEI can be found in the file AEI_PROTOCOL.md.

The scripts included for working with an AEI engine are:

• analyze - A simple script that runs an engine and has it search a given position or move sequence.
• gameroom - AEI controller that connects to the arimaa.com gameroom and plays a game.
• postal_controller - Keeps a bot making moves as needed in any postal games it is a participant in.
• pyrimaa_tests - Test runner utility.
• roundrobin - Plays engines against each other in a round robin tournament.
• simple_engine - Very basic AEI engine, just plays random step moves.

Basic examples of using the scripts can be found in the file USAGE.md.

The pyrimaa package also includes modules implementing the controller side of the AEI protocol (aei.py), the Arimaa position representation (as bitboards in board.py), and a few utility functions for handling Arimaa timecontrols (util.py).

Installation

For CLI Tools (Recommended)

If you just want to use the command-line tools, install with uv:

uv tool install aei

This creates an isolated environment for the AEI tools and makes them available in your PATH automatically. You can immediately run commands like analyze, gameroom, roundrobin, etc. without managing virtual environments.

For Library Usage or Traditional Installation

If you need to import pyrimaa modules in your own Python code (for example, to use pyrimaa.aei, pyrimaa.board, or pyrimaa.util), use:

uv pip install aei

Or install from a source directory checkout:

uv pip install .

Or skipping uv and using plain pip:

pip install aei

For Development

If you're contributing to the AEI project, install in editable mode:

uv pip install -e .

Or with pip:

pip install -e .
