## CM20217: Foundations of computation 1

Owning Department/School: Department of Computer Science
Credits: 6
Level: Intermediate (FHEQ level 5)
Period: Semester 1
Assessment: CW 25%, EX 75%
Supplementary Assessment: CM20217 Mandatory Extra Work (where allowed by programme regulations)
Requisites: Before taking this unit you must (take CM10227 and take CM10228 and take CM10196) or (take MA10209 and take XX10190)
Description: Aims:
To introduce formal models of computation. To give students an appreciation of the complexity of different algorithms and problems and the limits of computation. To provide students with a basic understanding of formal computational models such as finite state automata and Turing machines.

Learning Outcomes:
On completion of this unit, students will be able to:
1. demonstrate an understanding of the fundamental models of computation.
2. explain the notion of complexity class, and establish what classes a range of well-known problems belong to.
3. demonstrate that some computational problems are undecidable.

Skills:
Use of IT (A), Application of Number (T/F, A), Problem Solving (T/F, A).

Content:

* Models of computation: for example, basic notions of finite state automata, Turing Machines, register machines.
* Decidability. The undecidability of the Halting Problem. Reduction of other problems to the halting problem.
* Complexity. Big-O notation and complexity of algorithms. The notion of complexity class as a measure of the difficulty of a problem. Reduction between problems. Hardness and completeness of a problem with respect to a complexity class. The hierarchy of complexity classes. The question of whether P=NP and its importance for computer science.
