No other volume provides as broad, as thorough, or as accessible an introduction to the realm of computers as A. K. Dewdney's "The Turing Omnibus. " Updated and expanded, "The Turing Omnibus" offers 66 concise, brilliantly written articles on the major points of interest in computer science theory, technology, and applications. New for this tour: updated information on algorithms, detecting primes, noncomputable functions, and self-replicating computers--plus completely new sections on the Mandelbrot set, genetic algorithms, the Newton-Raphson Method, neural networks that learn, DOS systems for personal computers, and computer viruses.
