This book constitutes the refereed proceedings of the 7th International Conference on Unconventional Computation, UC 2008, held in Vienna, Austria, in August 2008. The 16 revised full papers presented together with 4 invited papers were carefully reviewed and selected for inclusion in the book. The papers are devoted to all aspects of unconventional computation ranging from theoretical and experimental aspects to various applications. Typical topics are: natural computing including quantum, cellular, molecular, neural and evolutionary computing, chaos and dynamical system-based computing, and...

The 8th International Conference on Unconventional Computation, UC 2009, was held in Ponta Delgada during September 7-11,2009, and was organized - der the auspices of the European Association for Theoretical Computer Science (EATCS) bythe Universityof Azores(Ponta Delgada, Portugal)and the Centre for Discrete Mathematics and Theoretical Computer Science (Auckland, New Zealand). The venue was the University of Azores, with its modern and well-equipped auditoria, next to the magni?cent rectory, and surrounded by a pleasant and peaceful garden.
