Computation is an intrinsic feature of natural and artificial systems because almost all of them can transform information in a predictable or programmable way. We witness experimentalprototypes of natural computers: plasmodium computers, reaction-diffusion processors, amorphous computers, DNA computers, and theoretical paradigms: cellular Automata, artificial chemistries, P-systems, evolutionary computing,neural networks. Fine mechanics of computation may significantly differ from system to system, and even be somewhere ambiguous. Present workshop aims to bring together computerscientists, biologists, mathematicians, electronic engineers, physicists and humanitarians, to critically assess present findings in the field, and to outline future developments in nature-inspiredcomputing.
