Chess Tuning Tools

A collection of tools for local and distributed tuning of chess engines.

• Free software: Apache Software License 2.0
• Documentation: https://chess-tuning-tools.readthedocs.io.

Features

• Optimization of chess engines using state-of-the-art Bayesian optimization.
• Support for automatic visualization of the optimization landscape.
• Scoring matches using the pentanomial model for paired openings.

Quick Start

In order to be able to start the tuning, first create a python environment and install chess-tuning-tools by typing:

pip install chess-tuning-tools

Furthermore, you need to have cutechess-cli in the path. The tuner will use it to run matches.

To execute the local tuner, simply run:

tune local -c tuning_config.json

Take a look at the usage instructions and the example configurations to learn how to set up the tuning_config.json file.

Distributed tuning

The distributed tuning framework is currently not actively supported. To be able to run the tuning client, you need the following directory structure:

folder/
|---- networks/
|     |---- networkid
|---- openings/
|     |---- ...
|     |---- openings.pgn
|     |---- ...
|---- dbconfig.json
|---- engine1[.exe]
|---- engine2[.exe]

Finally, the tuning client can be started as follows:

cd path/to/folder
tune run-client dbconfig.json

The client can be terminated gracefully by inputting ctrl-c once or terminated immediately by sending it twice.

You will also need to run a PostgreSQL database, which the server will use to post jobs for the clients to fetch and the clients to report their results to.
