## Overview

This course builds on the first-year Design and Analysis of Algorithms course. It introduces students to a number of highly efficient algorithms and data structures for fundamental computational problems across a variety of areas. Students are also introduced to techniques such as amortised complexity analysis. As in the first-year course, the style of the presentation is rigorous but not formal.## Learning outcomes

On successful completion of the course students will:

- Understand the implementation, complexity analysis and applications of fundamental algorithms such as max flow and linear programming
- Be able to analyse and use some fundamental data structures, such as binary search trees and disjoint sets
- Have some familiarity with randomised algorithms, approximation algorithms, and fixed parameter algorithms

## Syllabus

- Amortised analysis
- Disjoint sets / union-find
- Binary search trees (Red-Black trees, splay trees)
- Max flow and min cut in networks; applications
- Linear programming
- NP-hardness
- Approximation algorithms
- Fixed-paramter tractability
- Exponential algorithms
