Course details

Regulated Grammars and Automata

RGD Acad. year 2020/2021 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):

  • Regulated automata a grammars: basic idea.
  • Grammars with regulated use of rules.
  • Grammars with context-based regulation.
  • Regulated grammars based on algebraic restrictions.
  • Reduction of regulated grammars.
  • Parallel versions of regulated grammars.
  • Regulated finite automata.
  • Regulated pushdown automata.
  • Deep pushdown automata.
  • Jumping automata.

Subject specific learning outcomes and competences

Thorough grasp of concepts and results achieved in regulated rewriting in formal language theory and its applications.

Learning objectives

Students will obtain an in-depth overview of models and results concerning regulated rewriting in modern theoretical computer science. Most importantly, they will  improve their ability to use these theoretical knowledge in their own research.
