Course detail

Regulated Grammars and Automata

FIT-RGDAcad. year: 2020/2021

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.

Aims

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.

Specification of controlled education, way of implementation and compensation for absences

1. Two papers during the semester:
  • 20 points each = 15 for essay + 5 for presentation.
  • The topic has to be related to the topic of the course and approved by guarantee (Prof. Meduna).
  • After the presentation, the paper can be improved and re-submitted.

2. Oral exam consists of two questions, 30 points each.
