 Synopsis:

The course is presented in Czech.
The course covers the basics from the efficient algorithm design, data structures, and graph theory, belonging to the core knowledge of every computing curriculum. Students learn techniques of proofs of correctness of algorithms and techniques of asymptotic mathematics for estimation of their complexity in the best, worse, or average case (the course includes basics from probability theory needed for understanding randomized algorithms). Within exercises students learn applications of studied algorithms for solving practical problems.
 Requirements:

Entry knowledge: Active algorithmic skills for solving basic types of computational tasks, programming skills in some HLL (Java, C++), and knowledge of basic notions from the mathematical analysis and combinatorics are expected. Students are expected to take concurrent courses BIEAAG and BIEZDM.

4. Transformations and compositions of FA.
5. FA with output function and its implementation.
6. Conversions of grammars to FA and vice versa.

9. Creation and implementation of lexical analyzers.
10. Classification of languages.

 Study Objective:

The course covers the most basic of effective algorithms, data structures and graph theory, which should be known to every computer scientist. they will learn to use asymptotic mathematics practically.
