The framework supports a wide array of game types, including n-player (single- and multi-agent) zero-sum, cooperative, and general-sum games. It accommodates one-shot and sequential games, strictly turn-taking and simultaneous-move scenarios, and games with perfect and imperfect information. Beyond traditional games, OpenSpiel also encompasses traditional multi-agent environments like grid worlds and social dilemmas, supporting both partially and fully observable states.
OpenSpiel is built with a focus on research extensibility. It includes tools for analyzing learning dynamics and evaluating common metrics. Games are represented as procedural extensive-form games, with core APIs and game logic implemented in C++ and exposed to Python for ease of use. Algorithms and supplementary tools are developed in both C++ and Python, offering flexibility for different research needs.
For those looking to get started, OpenSpiel provides detailed documentation on installation for Linux and MacOS, with separate instructions for Windows. It includes an introduction to the API, an overview of implemented games and algorithms, and a developer guide for using OpenSpiel as a C++ library. Tutorials are available, including interactive Google Colaboratory notebooks, to guide users through core concepts, API usage, and implementing algorithms like CFR and REINFORCE on various poker games.
The project encourages community contributions and adheres to Semantic Versioning. Researchers are invited to cite the OpenSpiel paper when using the framework in their work. The project is licensed under the Apache-2.0 license, promoting open collaboration and innovation in the field of artificial intelligence and game theory.
