Course details

Selected Topics on Language Parsing and Translation

APD Acad. year 2025/2026 Winter semester

Current academic year

This course discusses selected advanced topic on language parsing and compilation. It concentrates especially on the recent research results from the studied area. Nevertheless, it also presents topics usually not discussed because of their complexity even if the topics are not new. In details, it is presented theory of the parsing and compilation together with practical aspects of analyzer/compiler construction.

Doctoral state exam - topics:

  1. LL (k) languages and their syntax analysis.
  2. LR and LALR languages and their syntax analysis, parsing table creation.
  3. Semantic and context addicted lexical analysis.
  4. Attributed grammars and their use for formal language analysis.
  5. Scattered context grammars and their variants, mutual relation of these variants, properties.
  6. Relation of scattered context grammars and their variants to Chomsky formal language hierarchy.
  7. Regulated pushdown automata, deterministic variants, relation to TM.
  8. LL scattered context grammars as an input for formal language analysis, construction of regulated pushdown automata.
  9. Practical implementation of parser/analyzer based on scattered context grammars - variants, optimization, limitations.
  10. The role of priorities and attributes for parsing/analyzing formal languages exploiting scattered context grammars.
