This book constitutes the refereed proceedings of the 12th European Conference on Genetic Programming, EuroGP 2010, held in Istanbul, Turkey, in April 2010 co-located with the Evo* 2010 events. This 28 revised full papers were carefully reviewed and selected from 48 submissions. The wide range of topics in this volume reflect the current state of research in the field, including representations, theory, operators and analysis, novel models, performance enhancements, extensions of genetic programming, and various applications.
