The Robot Auto Racing Simulator (RARS) consists of a simulation of the physics of cars racing on a track, a graphic display of the race, and a separate control program (robot "driver") for each car. The goal of the game is to implement such a control program in order to compete against other programmers. An official formula one season is held every year.
The OpenAI site is centered around an Open Source project and community involving artificial intelligence. The project itself is the creation of a set of tools that are considered to be models of human intelligence or biomimicry. These tools are intended to be integrated into applications or used stand alone for research.
Kalyp is a fantasy-based roguelike game written in Java. Its design is based on traditions set by popular roguelike games, especially Nethack. It is single player and runs in a text terminal. The project focuses mostly on the Artificial Intelligence engine for the non-player characters. Most of the game design will be done in scripting, as the core engine written in Java will handle user interface, rulesets, basic actions, and try to hold it all together.
JASA is a high-performance auction simulator. It is designed for performing experiments in agent-based computational economics. It implements variants of the double-auction market, which is commonly used to run real-world market places such as stock exchanges. It is designed to be highly extensible so that other types of auctions can easily be implemented. The software also provides a base classes for implementing simple adaptive trading agents.
