I am developing a model based on Markov Decision Process and I would like to test it on TORCS. To model the transitions of my TORCS-robot it could be very useful for me to know the equations that link the TORCS-controls (brake, steering, acceleration) with the corresponding new position of the car. To infer them form the source code is not trivial for me, can you help me to know these equations (also a good approximation is good) or where I could find them?
