The application of on-line learning techniques to modern computer games is a promising research direction. In fact, they can be used to improve the game experience and to achieve a true adaptive game AI. So far, several works proved that neuroevolution techniques can be successfully applied to modern computer games but they are usually restricted to offline learning scenarios. In on-line learning problems the main challenge is to find a good trade-off between the exploration, i.e., the search for better solutions, and the exploitation of the best solution discovered so far. In this paper we propose an on-line neuroevolution approach to evolve non-player characters in The Open Car Racing Simulator (TORCS), a state-of-the-art open source car racing simulator. We tested our approach on two on-line learning problems: (i) on-line evolution of a fast controller from scratch and (ii) optimization of an existing controller for a new track. Our results show that on-line neuroevolution can effectively improve the performance achieved during the learning process.
