Objectives and competences

A student gets an overview of the following discrete mathematics fields: discrete geometry, combinatorics and graph theory. During the study the connection with other fields of mathematics are emphasized.

Intended learning outcomes

Knowledge and understanding: General understanding of broad spectrum of discrete mathematical structures and in-depth knowledge about some of them.
Application: Mathematical structures from discrete mathematics have applications in optimization and computer programming, and play an important role in some other fields of mathematics.
Reflection: Connection of theoretical knowledge with practical applications, for instance in optimization, computer programming and other fields of mathematics. Capability of recognizing problems that could be successfully described by discrete mathematical models.
Transferable skills: Through the presentation of various selected examples a student gets familiar with various methods for proving mathematical results and gets insight into connections between different fields of mathematics. It becomes capable of reading and understanding of expert literature on discrete mathematics and other closely related fields.
