title: Arms races and car races creator: Togelius, Julian creator: Lucas, Simon M. subject: Machine Learning subject: Neural Nets subject: Artificial Intelligence description: Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences are found along this continuum; further, a tendency to specialization and the reactive nature of the controller architecture are found to limit evolutionary progress. publisher: Springer date: 2006 type: Conference Paper type: PeerReviewed format: application/pdf identifier: http://cogprints.org/5220/1/Togelius2006Arms.pdf identifier: Togelius, Julian and Lucas, Simon M.
