Thisbookcontainsthearticlespresentedatthe11thInternationalConferenceon theSimulationofAdaptiveBehavior(SAB2010),whichwasheldattheMuseum d'Histoire Naturelle and at the University Pierre et Marie Curie of Paris during August 25-27, 2010. On August 28, the attendees moved to Le Clos Luc'e-the last home of Leonardo da Vinci - where the 20th anniversary of the conference was celebrated. Theobjectiveofthe biennialSAB Conferenceis to bringtogether researchers incomputerscience,arti?cialintelligence,arti?ciallife,complexsystems,robotics, neurosciences, ethology, evolutionary biology, and related ?elds so as to further our understanding of the behaviors and underlying mechanisms that allow n- ural and arti?cial animals to adapt and survive in uncertain environments. Adaptive behavior research is distinguished by its focus on the modelling and creation of complete animal-like systems, which - however simple at the moment - may be one of the best routes to understanding intelligence in natural and arti?cial systems. The conference is part of a long series that started with the ?rst SAB Conference held in Paris in September 1990, which was followed by conferences in Honolulu 1992, Brighton 1994, Cape Cod 1996, Zu .
.rich 1998, Paris 2000, Edinburgh 2002, Los Angeles 2004, Rome 2006 and Osaka 2008. In 1992, the MIT Press introduced the quarterly journal Adaptive Behavior, now publishedbySAGE Publications. TheestablishmentoftheInternationalSociety forAdaptiveBehavior(ISAB) in1995furtherunderlinedtheemergenceofad- tive behavior as a fully ?edged scienti?c discipline. The present proceedings are a comprehensive and up-to-date resource for the latest progress in this exciting ?eld.
