This book contains the proceedings of the 11th Scandinavian Conference on Artificial Intelligence (AI), held in Trondheim in May 2011. It presents 17 full papers and an additional six short papers and posters carefully selected from the submissions after thorough peer review. The papers are arranged in four main sections: machine learning, planning, application of AI and robotics and cognition. Topics covered in the first section include: performance user-centered qualities generated by supervised learning algorithms; parallel implementation of the random forests algorithm and a spatial clustering algorithm for management zone delineation. The planning section includes papers on parallel plans; including velocity constraints for trajectory planning on grids; and path consistency to solve the Boolean satisfiability problem. Application of AI addresses subjects such as anomaly detection, as well as accurate motion compensation in minimally invasive treatment. Finally, the robotics and cognition section includes contributions on how relatively simple attractor dynamics can produce complex behavior and a knowledge-based system for supporting the reconfiguration of industrial robots. With its broad range of subjects, this book will be of interest to all those with an interest in, or whose work involves AI.IOS Press is an international science, technical and medical publisher of high-quality books for academics, scientists, and professionals in all fields.
