 Short Description:
The aim of this paper is to present mathematical models for computers and computation, and derive results about what can and cannot be computed. It deals with idealised computers (automata) which operate on idealised input and output (formal languages). For example, we prove that it is impossible to write a computer program that takes as input any computer program and tells us whether or not that program will end up in an endless loop (the halting problem). Quantum computing will also be briefly described and the ChurchTuring Thesis will be critically discussed. In addition we will discuss some problems in algorithmic complexity. We assume you are comfortable with formal mathematical proofs and can write them properly.
