The work described in this book was first presented at the Eighth Workshop
on Genetic Programming, Theory and Practice, organized by the Center for the
Study of Complex Systems at the University of Michigan, Ann Arbor, May
20-22, 2010. The goal of this workshop series is to promote the exchange of
research results and ideas between those who focus on Genetic Programming
(GP) theory and those who focus on the application of GP to various realworld
problems. In order to facilitate these interactions, the number of talks
and participants was small and the time for discussion was large. Further,
participants were asked to review each other’s chapters before the workshop.
Those reviewercomments, aswell as discussion at theworkshop, are reflected in
the chapters presented in this book. Additional information about theworkshop,
addendums to chapters, and a site for continuing discussions by participants and
by others can be found at http://cscs.umich.edu/gptp-workshops/ .
We thank all the workshop participants for making the workshop an exciting
and productive three days. In particular we thank the authors, without whose
hard work and creative talents, neither the workshop nor the book would be
possible. We also thank our keynote speaker J¨urgen Schmidhuber, Director
of the Swiss Artificial Intelligence Lab IDSIA, Professor of Artificial Intelligence
at the University of Lugano, Switzerland, Head of the CogBotLab at TU
Munich, Germany, and Professor SUPSI, Switzerland. J¨urgen’s talk inspired a
great deal of discussion among the participants throughout the workshop.
