Philip J. Boland,Harshinder Singhn this chapter we construct the universal Turing machine. This means that the universal Turing machine can behave like any Turing machine with any input if the description of the Turing machine to be simulated is given together with its input. On the other hand, there exists a limit to the computati

This fact naturally leads us to classify real-world problems into two types: . problems, which can be computed in a feasible amount of time, and . problems, which cannot be computed in a feasible amount of time. In order to classify problems we employ a Turing machine a

Each cell of the table can be regarded as a generalized gate that can be implemented by a certain number of Boolean gates under a suitable encoding. This circuit

Preliminaries to the Theory of ComputationIn this chapter, we explain mathematical notions, terminologies, and certain methods used in convincing logical arguments that we shall have need of throughout the book.

MAPLE

Roman Boutellier,Rochus A. Koblerton. Corresponding to the pumping lemma for regular languages, we introduce a pumping lemma for context-free languages, which shows that a language does not belong to the class of context-free languages. Context-free grammar are also used to describe practical programming languages.

Philip J. Boland,Harshinder Singh problem that any Turing machine cannot solve, we give the Post correspondence problem. The Post correspondence problem asks whether or not, when a collection of pairs of strings is given, there exists a sequence of the pairs (repetitions permitted) that has certain properties of a match.
