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


Algorithms are at the heart of computer science. In this module we will develop a range of core algorithmic ideas such as dynamic programming, greedy methods, divide-and-conquer techniques, and network flows. We will then learn how to use these to design efficient algorithms for a range of problems, motivated by a range of applications. We will then consider core concepts from computational complexity theory such as NP-completeness, and their implications for algorithm design. Finally, we will consider some advanced modern topics such as approximate and randomized algorithms, parameterized algorithms and complexity, and algorithms for streams of data.
