Further information on descriptions Description: Aims:
To introduce formal models of computation: finite automata, pushdown automata, Turing machines, and the corresponding classes of formal languages: regular, context-free, semi-decidable. To teach students to design algorithms for concrete computational problems within these models of computation. To introduce the dichotomy between deterministic and non-deterministic computation.
To give students an appreciation of limits of computation, including methods of proving undecidability and specific examples of undecidable problems. To introduce the concept of computational complexity and complexity classes.

Learning Outcomes:
On completion of this unit, students will be able to:
1. demonstrate an understanding of the fundamental models of computation and the corresponding classes of formal grammars and languages;
2. design algorithms for specific computational problems as automata of appropriate types;
3. demonstrate the practical application of grammars and language in to context of parsing algorithms
4. prove mathematically that some computational problems are undecidable within a particular class of computational models;
5. give upper bounds on complexities of some decidable computational problems.
6. put the theory in to practice by creating a parser for a specific language
