Languages, automata and grammars

Enrollement in the course requires an assessment of the following courses:

Discrete mathematics (AE4B01DMA)

Lecturer:

Tutor:

Supervisor:

Department of Mathematics

Synopsis:

The course covers basics of the theory of finite automata and grammars: deterministic and nondeterministic finite automata, characterization of the class of languages accepting by a finite automaton and description of such a language by a regular expression. Grammars and languages generated by a grammar, context-free grammars will be emphasized. The relation will be shown between context-free grammars and push down automata. Next topic is a Turing machine and the existence of non-decidable problems.
