This book constitutes the refereed proceedings of the 12th International Conference on
Unconventional Computation and Natural Computation UCNC 2013 held in Milan Italy in July
2013. The 30 papers (28 full papers 8 poster papers and 2 invited papers) were carefully
reviewed and selected from 46 submissions. The topics of the volume include: quantum cellular
molecular neural DNA membrane and evolutionary computing cellular automata computation
based on chaos and dynamical systems massive parallel computation collective intelligence
computation based on physical principles such as relativistic optical spatial
collision-based computing amorphous computing physarum computing hypercomputation fuzzy and
rough computing swarm intelligence artificial immune systems physics of computation
chemical computation evolving hardware the computational nature of self-assembly
developmental processes bacterial communication and brain processes.
