Computational complexity theory, also called algorithmic complexity theory, seeks to answertwo different kinds of questions: "How hard is this problem?", and "How effective is thisalgorithm at solving this problem?". A number of difficult issues are involved here, and it is not possible to delve into them deeply without sophisticated mathematics. Here we shall only…
When noise is added to the McCullough-Pitts network, it is no longer a Turing machine. It is astochastic computer — a computer which involves chance as well as the precise following ofinstructions. The error-ridden neural network is merely one type of stochastic computer. Everyreal computer is a stochastic computer, in the sense that it…
Mind and Computation1.0 Rules What does it mean to tell someone exactly what to do? Sixty years ago no one could give this query a plausible response. Now, however, we have agenerally accepted definition: a set of instructions is exact if some computer can follow them.We have a word, algorithm, which is intended to refer…
