Module summary

Algorithms and algorithmic problem solving are at the heart of computer science. This module introduces students to the design and analysis of efficient algorithms and data structures. Students learn how to quantify the efficiency of an algorithm and what algorithmic solutions are efficient. Techniques for designing efficient algorithms are taught, including efficient data structures, standard methods such as Divide-and-Conquer and Dynamic Programming as well as more advanced techniques for computationally intractable problems and large data sets. This is done using illustrative and fundamental problems relevant to AI.

Objectives

The aims of this module are to enable students to:

- appreciate and apply algorithmic thinking
- appreciate what constitutes an efficient and an inefficient solution to a computational problem;
- identify and apply design principles such as greediness, divide and conquer and dynamic programming;
- analyse and implement some fundamental algorithms;
- describe efficient algorithms for fundamental computational problems, along with their computational complexity.
- understand the difference between polynomial and exponential time algorithms;
- know how NP-hard problems can be dealt with in practice;
- appreciate selected cutting-edge modern algorithms;
- articulate the key concepts and justify approaches in a clear and rigorous manner

Teaching methods

Delivery type	Number	Length hours	Student hours
On-line Learning	6	1.00	6.00
Group learning	6	2.00	12.00
Independent online learning hours			28.00
Private study hours			104.00
Total Contact hours			18.00
Total hours (100hr per 10 credits)			150.00

Private study

Private study will include directed reading and exercises and self-directed research in support of learning activities, as well as in preparation for assessments.

Independent online learning involves non-facilitated directed learning. Students will work through bespoke interactive learning resources and activities in Minerva.

Opportunities for Formative Feedback

Online learning materials will provide regular opportunity for students to check their understanding (for example through formative MCQs with automated feedback). Regular group activity embedded into learning will allow self and peer assessment providing opportunities for formative feedback from peers and tutors.
