Synopsis

This unit gives an introduction to formal languages using logic programming and looks at what a computer can compute and what problems are intractable. Examples include why it is so difficult to design timetables, get computers to play Go, or crack a code. Topics include computable functions, finite state automata, regular expressions, grammars, Turing computability, polynomial-time reductions, and NP-completeness.

Objectives

At the completion of this unit, students will have -

A knowledge and understanding of:

  • propositional and predicate logic;
  • how to describe languages using Regular Expressions, Finite Automata, Nondeterministic Finite Automata, Context Free Grammars, Pushdown Automata, and Turing Machines;
  • the relationship between Regular Languages, Context Free Languages, Recursive Languages, and Recursive-Enumerable (or Computable) Languages;
  • how to use Turing Machines to represent computable functions;
  • how a Universal Turing machine can simulate any Turing Machine on any input;
  • basic computational complexity theory, including verifiers, polynomial-time reductions and NP-completeness.

Developed attitudes that will allow them to:
  • appreciate the limitations of Regular Languages, Context Free Languages, Recursive Languages, and Computable Languages;
  • comprehend the limitations of computers in terms of the problems they can solve;
  • appreciate that there are many solvable problems which cannot be solved in polynomial time.

Developed the skills to:
  • use propositional logic to represent and analysis problems in the theory of computation;
  • construct Finite Automata, Nondeterministic Automata, and Turing Machines to describe languages;
  • convert Regular Expressions into a Finite Automata;
  • convert Finite Automata into Regular Expressions;
  • find a Regular Grammar for a Regular Language;
  • find a parse tree, leftmost derivation and rightmost derivation for a word in a Context Free Language;
  • know how to show a Context Free Grammar is ambiguous;
  • show a problem is NP-complete.
