What is Theory of Computation?
Theory of Computation (TOC) is a branch of computer science that deals with how problems can be solved using mathematical models of computation. It explores the capabilities and limitations of computational machines and provides the foundation for designing efficient algorithms and compilers.
These notes will help you understand topics like:
Basics of Automata Theory
Finite Automata (DFA, NFA, ε-NFA)
Regular Expressions and Regular Languages
Context-Free Grammars (CFG) & Pushdown Automata (PDA)
Turing Machines
Chomsky Hierarchy of Languages
Computability and Decidability
Complexity Theory (P, NP, NP-Complete problems)
