The laws and methodology of physics are starting to provide powerful insights into the nature and dynamics of computation. This book contains a number of articles that illustrate how fields ranging from quantum mechanics to statistical physics and nonlinear dynamics can help elucidate the nature of computation. Contents:Quantum Limits on Information Transmission for Single and Many Channels Architectures (M Schiffer)Algorithmic Randomness, Physical Entropy, Measurements, and the Second Law (W H Zurek)Cooperative Problem Solving (S H Clearwater, T Hogg & B A Huberman)Directed-Graph Epidemiological Models of Computer Viruses (J O Kephart & S R White)The Use of Physics Concepts in Computation (G C Fox) Readership: Computer scientists and physicists. keywords: “The saving grace is the serious nature of the articles and the considerable number of useful references they provide in their respective areas.” Contemporary Physics
