Regulated Grammars and Automata

RGD Acad. year 2022/2023 Winter semester

Current academic year

This course discusses the regulated rewriting as an important topic in theoretical computer science during last years. It concentrates on the latest concepts and results in the area of regulated grammars and automata, including their application. The students will write a report about regulated rewriting in relation to their own research.

Topics for the state doctoral exam (SDZ):

  1. Regulated automata a grammars: basic idea.
  2. Grammars with regulated use of rules.
  3. Grammars with context-based regulation.
  4. Regulated grammars based on algebraic restrictions.
  5. Reduction of regulated grammars.
  6. Parallel versions of regulated grammars.
  7. Regulated finite automata.
  8. Regulated pushdown automata.
  9. Deep pushdown automata.
  10. Jumping automata.
