Academic Overview

Learning 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.

This teaching and learning approach provides facilitated learning, practical exploration and peer learning.


Our feedback to You

Types of feedback you can expect to receive in this unit are:
  • Informal feedback on progress in labs/tutes
  • Solutions to tutes, labs and assignments

Your feedback to Us

Monash is committed to excellence in education and regularly seeks feedback from students, employers and staff. One of the key formal ways students have to provide feedback is through SETU, Student Evaluation of Teacher and Unit. The University's student evaluation policy requires that every unit is evaluated each year. Students are strongly encouraged to complete the surveys. The feedback is anonymous and provides the Faculty with evidence of aspects that students are satisfied and areas for improvement.

For more information on Monash's educational strategy, and on student evaluations, see:

Assessment Requirements

Assessment Policy

To pass a unit which includes an examination as part of the assessment a student must obtain:

  • 40% or more in the unit's examination, and
  • 40% or more in the unit's total non-examination assessment, and
  • an overall unit mark of 50% or more.

If a student does not achieve 40% or more in the unit examination or the unit non-examination total assessment, and the total mark for the unit is greater than 50% then a mark of no greater than 49-N will be recorded for the unit

Assessment Tasks


  • Assessment task 1
    Pracs (3 hours)
    On alternating weeks (on five occasions) you will need to complete a prac assignment. Prac assignments are long and are designed to take a significant part of your "home study hours''. This means that you must have a significant proportion of the prac completed before attending the scheduled computer lab. The aim of the computer lab practical is to iron out any bugs, ask any questions about the prac you have not been able to solve on your own, improve the parts that your demonstrator points out as lacking (including comments, algorithms, etc), and get your prac marked. If you do nothing before the scheduled prac, you will soon realise that you do not have enough time to complete it.  The prac sheets will be released approx. every Thursday morning and/or made available in the unit's web page.

    Unless explicitly specified otherwise by both your lecturer and your prac demonstrator, your assignment work is to be done from your Monash student account and demonstrated on one of the Monash computers in your scheduled Monash lab.

    Total of 30% (5 pracs x 6%)
    Criteria for assessment:

    Every prac sheet contains a guide of the assessment criteria used to assess that prac. In addition, demonstrators might carry with them a marking guide prepared by the lecturer which indicates some details of the marks for each prac question.  You can request the demonstrator to show you the marking guide after he/she has marked your prac.

    Due date:
    • Week 4 - Prac 1: Finite Automata.
    • Week 6 - Prac 2: Lexical Analysis.
    • Week 8 - Prac 3: Parsing.
    • Week 10 - Prac 4: Computability.
    • Week 12 - Prac 5: Cook-Levin and Equivalence.
    There are two hurdles associated with the pracs. First, you must attend and submit/present at least 4 out of the 5 pracs. Second, you must score at least 50% of the prac mark. A student who does not meet all these hurdles can get a maximum of 49 N for the unit.

    The form(s) of your assignment submission - identical soft electronic and/or hard copies - will be elaborated upon in the assignment statement.  Your assignment will be deemed submitted when all of these versions are submitted.


  • Examination 1
    3 hours
    Type (open/closed book):
    Closed book
    Electronic devices allowed in the exam:
    There is a hurdle associated with the exam mark:
    • You must score at least 50% of the exam mark.
    • Furthermore, you must score at least 50% overall.

Assignment submission

It is a University requirement (http://www.policy.monash.edu/policy-bank/academic/education/conduct/plagiarism-procedures.html) for students to submit an assignment coversheet for each assessment item. Faculty Assignment coversheets can be found at http://www.infotech.monash.edu.au/resources/student/forms/. Please check with your Lecturer on the submission method for your assignment coversheet (e.g. attach a file to the online assignment submission, hand-in a hard copy, or use an online quiz).
