Brief Handbook Description:  This unit provides an introduction to the foundations of computational models  including Lambda Calculus (functional approach), Automata Theory (stateful approach), and Logic calculi (propositional and predicate logic, formal proofs). Practical use is illustrated by exploring programming languages based upon them, i.e. functional programming (e.g. Haskell) and logic programming, in contrast to the procedural languages most students will already be familiar with (e.g. Cstyle languages). The expressive power, and limitations, of different Automata is explored (e.g. Regular, ContextFree, and Recursivelyenumerable languages), culminating with Turing machines and the notions of computability and decidability. 
Assumed Knowledge:  MATH1004 OR MATH1904 OR MATH1064 OR MATH2069 OR MATH2969.

Time Commitment: 


T&L Activities:  Independent Study: Students are expected to undertake the prescribed reading and work on homework exercises and assignments. 
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.
Unassigned OutcomesAssessment Methods: 


Assessment Description: 
Weekly inclass exercises: short exercises to do inclass at the beginning of each tutorial. Assignments: the first 2 are individual assignments, which consist of a report and a programming part. The 3rd assignment is a formal proof, to be done individually or in pairs. Final Exam: 2 hour exam, paperbased 

Assessment Feedback:  Assignments are handed back within 2 weeks with written feedback. General feedback given in the lecture or in the tutorial. Solutions of tutorials are posted each week. 

Grading: 


Policies & Procedures:  IMPORTANT: School policy relating to Academic Dishonesty and Plagiarism. In assessing a piece of submitted work, the School of Computer Science may reproduce it entirely, may provide a copy to another member of faculty, and/or to an external plagiarism checking service or inhouse computer program and may also maintain a copy of the assignment for future checking purposes and/or allow an external service to do so. Other policies See the policies page of the faculty website at http://sydney.edu.au/engineering/studentpolicies/ for information regarding university policies and local provisions and procedures within the Faculty of Engineering and Information Technologies.

These goals are selected from Engineering & IT Graduate Outcomes Table 2018 which defines overall goals for courses where this unit is primarily offered. See Engineering & IT Graduate Outcomes Table 2018 for details of the attributes and levels to be developed in the course as a whole. Percentage figures alongside each course goal provide a rough indication of their relative weighting in assessment for this unit. Note that not all goals are necessarily part of assessment. Some may be more about practice activity. See Learning outcomes for details of what is assessed in relation to each goal and Assessment for details of how the outcome is assessed. See Attributes for details of practice provided for each goal.
