Contents

  • Automata theory and formal languages: grammars and the Chomsky hierarchy, finite automata and regular expressions, context-free grammars and push-down automata, closure properties of formal languages, decidability questions
  • Computability: models of computability: Turing, Loop and While-computability, primitive recursion and μ-recursion, Church-Turing thesis; decidability, enumerability, undecidable problems
  • Complexity theory: complexity measures; P and NP; reductions and NP-complete problems

Qualification Goals

Students

  • can deal with regular expressions, finite automata and grammars,
  • know their possibilities and limitations,
