Objectives and competences

Students learn the basics of mathematical proofs and correct logic inference, basic discrete structures, and the basics of graph theory.

Intended learning outcomes

Knowledge and understanding: Knowledge about basic concepts of logic, order structures and graph theory, and understanding of basic connections among them.
Application: Use of discrete mathematical structures for representation of various objects and processes. Such representations play a key role in data processing with computers.
Reflection: Connection of theoretical knowledge with applications, for instance in optimizations and computer programming. Capability of recognizing problems that could be successfully described by discrete mathematical models.
Transferable skills: Knowledge about basic approaches regarding use of discrete mathematical structures. Exactness at thinking and problem solving. Capability of reading and understanding of expert literature on discrete mathematics and other closely related fields.
