in this book, Christof Teuscher analyzes all aspects of Turing’s “unorganized machines”. Turing himself also proposed a sort of genetic algorithm to train the networks. This idea has been resumed by the author and genetic algorithms are used to build and train Turing’s unorganized machines. Teuscher’s work starts from Turing’s initial ideas, but importantly goes beyond them. Many new kinds of machines and new aspects are considered, e.g., hardware implementation, analysis of the complex dynamics of the networks, hypercomputation, and learning algorithms.
