# ADVANCED ALGORITHMS - 2020/1

Module code: COM2031

Module Overview

The module introduces algorithmic techniques for various sets of problems and teaches how to analyse algorithms in terms of their complexity. The techniques build upon the data structures and algorithms module provided in level 4 (COM1029) so that students can further develop their use of methods for solving complex problems. Examples will be used throughout to demonstrate the relevance of each approach.

Assessment Strategy

The __assessment strategy__ is designed to provide students with the opportunity to demonstrate that they have achieved the module learning outcomes.

Thus, the __summative assessment__ for this module consists of:

· An individual coursework on sets of problems that students are required to solve. This addresses LO1, LO2, LO3, LO4 and LO5.

· A 2h unseen examination on the whole course content. This addresses LO2, LO3, L05 and LO6.

The individual courseworks will be due around week 6. The exam takes place at the end of the semester during the exam period.

__Formative assessment and feedback__

Lecture slides are used extensively in the lectures with each lecture consisting of a number of slides explaining the theory and showing the examples. Solutions to lab exercises are explained during the lab session and provided to the students as part of preparation for the exam.

Module aims

- The aim of this module is to equip students with a tool box of efficient algorithmic techniques which they can apply to real-world problems. This will cover foundations, theoretical advantages and constraints of a broad range of algorithms. Mathematical algorithms and operational techniques will be presented using examples of problems allowing students to practice their application. Appropriate mathematical concepts will be introduced to support the theoretical design and evaluation of algorithms.

Overall student workload

Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to:

- Help students understand the distinctive features of a broad range of algorithmic techniques
- Deomonstrate the application of algorithmic techniques for solving concrete problems
- Explain students how to analyse the complexity of an algorithm, incl. its performance and how to compare different algorithms
- Equip students with necessary mathematical background to understanding certain algorithms
- Enable students to apply taught techniques to solve concrete problems

The

__learning and teaching__methods include:

- Lectures (11 weeks at 2h) using detailed lecture slides to gauge the students’ understanding
- Labs/Tutorials (11 weeks at 2h) using exercises and their solutions and demonstrations.

Students will be expected to spend a minimum of 7 hours a week on self-study to prepare and revise lecture, lab and tutorial material.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
