Aims
This fullyear course unit focuses on the use of mathematics as a tool to model and analyse realworld problems arising in computer science. Four principal topics, drawn from the traditional areas of discrete mathematics as well as some continuous mathematics, will be introduced: symbolic logic, probability, discrete structures, and vectors and matrices. Each topic will be motivated by experts introducing relevant realworld problems arising in their own specialism.
Abstraction is fundamental to computer science. Hence, a fundamental emphasis of this course unit is to introduce mathematical techniques and skills to enable the student to design and manipulate tractable and innovative abstract models of chunks of the realworld. These techniques and skills include appropriate mathematical notations and concepts. These range over the four principal areas mentioned above. Formalisation in mathematics has, in general, significant cost. Therefore, to be of practical use, the benefits arising from formalisation, such as succinctness, unambiguity, provability, transformability and mechanisability, must outweigh the costs. A key aim of the course is for the student to appreciate this issue and know how and when to use particular techniques.
The specific aims of the course unit are:
To demonstrate the relevance of mathematics to computer science.
To introduce fundamental mathematical techniques of abstraction.
To demonstrate applicability of particular mathematical techniques and skills for particular types of computer science problem.
To appreciate the costs and benefits of mathematical modelling.
The delivery style will place more emphasis on students undertaking appropriate background reading, i.e. being more independent learners, and use the lectures more to demonstrate examples and solutions and not working through every detail of a particular or concept.
The course unit is delivered by staff from both the School of Computer Science and the School of Mathematics .
