Arimaa Engine Interface tools

Project description

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 gameroom. A full description of AEI can be found in the file aei-protocol.txt.

The scripts included for working with an AEI engine are:


A simple script that runs an engine and has it search a given position or move sequence.


AEI controller that connects to the gameroom and plays a game.


Keeps a bot making moves as needed in any postal games it is a participant in.


Plays engines against each other in a round robin tournament.


Very basic AEI engine, just plays random step moves.

Basic examples of using the scripts can be found in the file usage.rst.

The pyrimaa package also includes modules implementing the controller side of the AEI protocol (, the Arimaa position representation (as bitboards in and x88 in, and a few utility functions for handling Arimaa timecontrols (

If you have python2 and pip on your machine you can install the latest release with:

pip install aei

On an operating system with a system supplied python you probably want to keep the aei install separate from your system installed packages. To accomplish that you can use either a virtualenv or user install. A user install is done simply by adding the --user option:

pip install --user aei

AEI may also be built and installed with

python install
