RARS is the Robot Auto Racing Simulation, a competition for programmers and an on-going challenge for practicioners of Artificial Intelligence and real-time adaptive optimal control.  It 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.  All RARS software and activities are free and open to the public.  It runs on DOS, Windows, OS/2, UNIX, Linux, and several other platforms.

The introduction was token from Ralph Scott's introduction.
