Rules for evaluation and completion of the course

Tests during the semester
The subject is evaluated according to the result of the final exam, the minimum for passing the exam is 50/100 points.

Aims

The aim of the subject is to acquaint students with modern mathematical methods used in informatics. In particular, methods based on the theory of ordered sets and lattices, algebra and topology will be discussed.  
Students will learn about modern mathematical methods used in informatics and will be able to use the methods in their scientific specializations.
The graduates will be able to use modrn and efficient mathematical methods in their scientific work.
