Intended learning outcomes *

The general objective is to give basic knowledge in Discrete Mathematics, especially in the solution of combinatorial problems, the knowledge of some important algebraic structures and basic knowledge of graph theory. Also the ability to perform a stringent mathematical discussion is trained.

After passing the course a student should be able to

  • formulate basic theorems and definitions of important concepts in discrete mathematics,
  • apply theorems and methods in discrete mathematics.
