# turing machine

A Turing machine is a mathematical model of computation that defines an abstract machine, which manipulates symbols on a strip of tape according to a table of rules. Despite the model’s simplicity, given any computer algorithm, a Turing machine capable of simulating that algorithm’s logic can be constructed.

This paper has two purposes. The first is to investigate the characteristics of a restricted class of Turing machines, and to develop a simple tool for describing their computations. The second is to present specific problems for which tight lower bounds can be found for the One of the most important problems in complexity theory is that for separating complexity classes such as A, NA or P(or to prove their coincidence). Recently the following approach proves to be quite successful. One describes the complexity classes under consideration by I became interested in Conways Game of Life in the 1980s when I wrote a Game of Life program for an Amstrad CPC 464. This little computer with 64K of memory ran on a Z80 microprocessor with a 4 MHz clock. The program had a closed universe of 64 128 cells

Gilbert Simondon once noticed that industrial machines were already information relays, as they were bifurcating for the first time the source of mechanical work (the natural energy) from the source of information (the worker). In 196 in order to describe the new condition of

(This is known as system 0in the proof below.) The proof I intend to give demonstrates that this Turing machine can emulate any two-colour cyclic tag system for an infinite number of steps; in order to do this, I first show that this Turing machine can emulate any two-colour

** A Turing machine space hierarchy**

This paper introduces a new, finer space complexity measure of computations on Turing machines. The complexity of a computation on a Turing machine now takes into account also the capacity of the finite control. It is proved that a slight enlarging (by an additive

We naturally extend Aleksanders logical neural networks and show how this extended model simulates the behaviour of a Turing machine . It is widely believed that the only truly neural simulation of a Turing machine should be internal. As a consequence authors have

In , it was shown that every language accepted by an S (n) tape-bounded probabilistic Turing machine can be accepted by a deterministic Turing machine within tape O (S (. In this note, we extend this result by showing that S (n) tape-bounded probabilistic machine

It is often maintained that the brain-as-computer metaphor is ill taken. Nevertheless one can view conscious cognition as a Turing Machine process, Turing (1937), with its discrete, deterministic, and universal aspects. Not being used to the language of science one may

Problems in implementing DNA and other types of molecular computers stem from the inherent physical nature of molecules and their reactions. The current theory of computation makes assumptions that at best are very crude approximations of the physical chemistry. A

The paper introduces three complexity measures of computations on Turing machines with oracles. The complexity of a computation on a Turing machine with an oracle is given either by the number of interactions with the oracle during the computation, or by the sum of the
