This book constitutes the proceedings of the 16th International Conference on Unconventional Computation and Natural Computation, UCNC 2017, held in Fayetteville, AR, USA in June 2017. The 14 papers presented in this volume were carefully reviewed and selected from 21 submissions. The UCNC series of international conferences is genuinely interdisciplinary and it covers theory as well as experiments and applications. It is concerned with various proposals for computation that go beyond the Turing model, human designed computation inspired by nature, and with the computational nature of processes taking place in nature. Typical, but not exclusive, topics are: hypercomputation; chaos and dynamical systems based computing; granular, fuzzy and rough computing; mechanical computing; cellular, evolutionary, molecular, neural, and quantum computing; membrane computing; amorphous 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.
