This module introduces graph theory, graph theoretic algorithms and graph databases. Students will be able to recognise data-analysis problems with an underlying graph-theoretic component, and design and build software solutions to those problems.

Learning Outcomes

1. Recognise graph theoretical components of real world data-analysis problems.
2. State and prove core graph theoretical results.
3. Choose appropriate graph algorithms for solving graph theoretical problems.
4. Appreciate the computational complexity of graph-theoretical solutions.
5. Write computer programs to solve graph theoretical problems.
6. Develop problem-solving skills which are applicable to graph theory and general areas of data science.
