On successful completion of the course, the student
- is able to evaluate the possible extent of using the methods of
finite automata, context-free grammars etc. by solving concrete
practical problems, and is able to design, analyse and compare the
respective solutions
- is able to analyse computational complexity of practical problems,
and to design algorithms for their solution
- understands the notions like approximation algorithms, probabilistic
algorithms, etc. and can evaluate the possibilities of their use in
concrete practical situations

Projects:
Each student will be assigned a selected topic related to the contents
of the course (at the beginning of semester).
The student will study the topic from the recommended or freely
chosen sources. He/she will then elaborate his/her own text which will
consicely explain the main ideas, within the given deadline and in (at
least) the minimal given extent.
The author will personally present the topic at some exercise session
or in another way determined by the lecturer.
