Mathematical Techniques for Computer Science

Level 2/I

Achim Jung Semester 1 10 credits
Co-ordinator: Achim Jung
Reviewer: Steven Vickers

The Module Description is a strict subset of this Syllabus Page.


Computer Science makes use of a variety of mathematical techniques to describe and solve computational problems. Often, these techniques are quite deep and outside the scope of standard mathematical syllabuses, for example, the use of structural recursion in the analysis of data structures and programming languages. The module aims to present a core of mathematical techniques in a sample computational context, and tries to strike a balance between systematic introduction and an application-orientated "maths-by-need" approach.


The aims of this module are to:

  • present mathematical techniques that underly Computer Science
  • present these techniques in a sample Computer Science context
  • illustrate the power of mathematics in solving problems in Computer Science
  • provide an introduction to Linear Algebra, Set Theory, and Probability

Learning Outcomes

On successful completion of this module, the student should be able to:

  1. solve simple mathematical problems in the areas covered by the module
  2. apply a given mathematical technique to solve a problem within a computer science setting
