Content, Learning Outcome and Preconditions
Regular languages: DFA, NFA with and without ε-transitions, regular expressions and translations between them; systems of language equations; closure under boolean operations; Arden’s lemma; pumping lemma; decision problems; minimization; Myhill-Nerode theorem.
CFLs: PDAs and translation between CFGs and PDAs; proof that DPDAs are weaker than PDAs; closure properties; CYK algorithm; pumping lemma; Chomsky and Greibach normal forms.
Context-sensitive languages and LBAs.
Computability: computability, decidability, semi-decidability, recursive-enumerability and their relationships; existence of non-computable problems; Turing machines, accepted languages, type-0 languages: equivalence of Turig machines, While-programs and Goto-programs; primitive and µ-recursive functions; reductions between problems; the Halting problem; universal Turing machines; Rice’s theorem; Rice-Shapiro theorem; undecidability of the Post Correspondence Problem and important problems on CFGs.
Complexity theory: time and space complexity classes; polynomial-time reductions; the classes P and NP; NP-completeness; Cook’s theorem; important NP-complete problems and reductions between them.
All proofs are covered.
