Unconventional Computation: 8th International Conference, Uc 2009, Ponta Delgada, Portugal, September 7-11, 2009, Proceedings: Vol 5715

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. The university is located in the city of Ponta Delgada, on S˜ ao Miguel Island, in the Archipelago of the Azores. Sao ˜ Miguel is famous for its beautiful landscapes and exceptional volcanic lakes. Depending on the s- rounding countryside, some appear peaceful and relaxing, while others are more dramatic. Ponta Delgada has many magni?cent buildings of tremendous arc- tectural value portraying the urban architecture of the sixteenth to nineteenth centuries. The majority of these are presently used to accommodate various - litical, administrative, religious and cultural o?ces. There are several churches that are authentic works of art, with Gothic structures and Manueline exteriors. Others are in the baroque style, with interior embroideries in gold thread and rare wood pieces. Famous paintings are also easily found in Ponta Delgada. The International Conference on Unconventional Computation (UC) series is devoted to all aspects of unconventional computation - theory as well as experiments and applications.
