Stack Automata: Formal Definition

Covers deterministic pushdown automata and their use in language recognition.

Explores Turing machines, recursive languages, undecidability, and symbol elimination.

Covers the basics of computational complexity, including big O notation and complexity classes.

Covers context-free grammars, their equivalence to pushdown automata, and the hierarchy of grammar types.

Explores computational complexity, NP-completeness, and polynomial reductions in theoretical computer science.
