Learning classifier systems : 11th international workshop, IWLCS 2008, Atlanta, GA, USA, July 13, 2008, and 12th international workshop, IWLCS 2009, Montreal, QC, Canada, July 9, 2009 : revised selected papers

This book constitutes the thoroughly refereed joint post-conference proceedings of two consecutive International Workshops on Learning Classifier Systems that took place in Atlanta, GA, USA in July 2008, and in Montreal, Canada, in July 2009 - all hosted by the Genetic and Evolutionary Computation Conference, GECCO. The 12 revised full papers presented were carefully reviewed and selected from the workshop contributions. The papers are organized in topical sections on LCS in general, function approximation, LCS in complex domains, and applications.
