Nonlinear Dynamics Perspective Of Wolfram’s New Kind Of Science, A (In 2 Volumes) – Volume I [PDF ebook] 

This novel book introduces cellular automata from a rigorous nonlinear dynamics perspective. It supplies the missing link between nonlinear differential and difference equations to discrete symbolic analysis. A surprisingly useful interpretations of cellular automata in terms of neural networks is also given. The book provides a scientifically sound and original analysis, and classifications of the empirical results presented in Wolfram’s monumental ’;New Kind of Science.’;
