Genetic Programming: 12th European Conference, EuroGP 2009 Tübingen, Germany, April, 15-17, 2009 Proceedings (Lecture Notes in Computer Science / Theoretical Computer Science and General Issues)

The 12th European Conference on Genetic Programming, EuroGP 2009, took place in Tu ¨bingen, Germany during April 15-17 at one of the oldest univer- ties in Germany, the Eberhard Karls Universitat ¨ Tubing ¨ en. This volume c- tains manuscripts of the 21 oral presentations held during the day, and the nine posters that were presented during a dedicated evening session and reception. The topics covered in this volume re?ectthecurrentstateoftheartofgenetic programming, including representations, theory, operators and analysis, feature selection, generalization, coevolution, and numerous applications. A rigorous, double-blind peer-review process was used, with each submission reviewed by at least three members of the international ProgramCommittee. In total, 57 papers were submitted with an acceptance rate of 36% for full papers and an overall acceptance rate of 52% including posters. The MyReview m- agement software originally developed by Philippe Rigaux, Bertrand Chardon, and other colleagues from the Universit´ e Paris-Sud Orsay, France was used for the reviewing process. We are sincerely grateful to Marc Schoenauer from IN- RIA, France for his continued assistance in hosting and managing the software. Paper review assigments were largely done by an optimization process matching paper keywords to keywords of expertise submitted by reviewers.
