Theory of Computation — GATE CS / IT

Theory of Computation — GATE CS / IT

The complete Theory of Computation syllabus, structured for GATE CS and IT. 15 chapters and 143 content pieces walk through regular and context-free languages, finite automata, pushdown automata, Turing machines, and the theory of computability and undecidability.

TOC is notorious for being conceptually dense but algorithmically straightforward once intuition clicks. The teaching style here is heavy on diagrams, worked-through automata constructions, and "convert this regex into a DFA"-style problems. The PYQ section covers every TOC question that has appeared in GATE — and there's at least one almost every year.
