### Discrete Mathematics 1

#### Learning Outcomes

1. To solve homogeneous and non-homogeneous linear recursion.
2. Apply the recursive way of thinking on the appropriate combinatorial problems.
3. Describe and manipulate with basic notions from graph theory.
4. Describe and solve appropriate engineering problems in terms of graph theory.
5. Solve problems algorithmically using computers.

#### Forms of Teaching

Lectures

4 hours of lectures a week. The lecturer is going to follow the lecture materials.

Independent assignments

During the semester 3 software excercises will be given to be solved by the students individually and to be shown in the framework of laboratory excercises.
