Cellular Automata

Designing Ultra-Dense Computers with QCAs
Quantum Cellular Automata, a new technology, can make real computers orders of magnitude denser than the limits of CMOS, from molecule size devices; information flows by Coulomb interactions not electric current. Investigators, references. [Notre Dame Computer Science and Engineering]

Evolution of Parallel Cellular Machines: The Cellular Programming Approach
By Moshe Sipper; Springer-Verlag, 1997, ISBN 3540626131. Man-made systems can have traits seen in natural collective systems, which evolve by selection processes to have problem-solving abilities; via simple, versatile parallel cellular models, and evolutionary computing. <small>(1997)</small>
