CSE 437: Theory of Computation and Automata

Offered Under: B.Sc. in Computer Science & Engineering (CSE)

This course introduces the mathematical foundations of all computation. Core concepts of automata, formal languages, grammar, decidability and computability will be discussed. Topics include: Basic notions: string, prefix, suffix, substring, concatenation; Cardinality; Distinction between uncountable and countable infinite; Different proof techniques: proof by construction, proof by contradiction, pigeon hole principle; Deterministic and non-deterministic  finite state automata; Regular language, regular expression; Equivalence of NFA and DFA; Pumping Lemma, non regular languages; Context free grammar (CFG) and push down automata (PDA; Chomsky normal form; Parsing; Turing machine, Universal Turing machine and Halting problem;  Goedel numbering; P/NP complexity.  Students taking this course should possess a strong background in discrete mathematics and data structures.

Expected Outcome(s):
  • Defineand describe formal models of computation, such as finite automata, pushdown automata, and Turing machines.
  • demonstrate their the understanding of key notions, such as algorithm, computability, decidability, and complexity through problem solving.
  • Convert between finite automata, regular grammars, and regular expression representations of regular languages.
  • Apply the pumping lemma for regular languages to determine if a language is regular.
  • Convert between grammars and push-down automata for context-free languages.
  • Applylearned concepts to create proofs regarding the computational complexity of various problems.
