CS3518: LANGUAGES AND COMPUTABILITY (2017-2018)

Last modified: 04 Jul 2017 10:13


Course Overview

This course provides a basic-level introduction to computability via the notion of a Turing Machine. Some familiarity with imperative programming (e.g., in JAVA) and with the basics of set theory (e.g., the notion of a bijection) is assumed. The Functional language Haskell (familiar from earlier courses, including CS2013) is used to explore the concepts of infinity, recognisability and decidability, which are crucial to computability.

72 hours

This is the total time spent in lectures, tutorials and other class teaching.

Teaching Breakdown


Assessment

1st Attempt: 1 two-hour written examination (75%); continuous assessment (25%).

Resit: 1 two-hour written examination (75%); continuous assessment mark carried forwards (25%).

Only the marks obtained on first sitting can be used for Honours classification.

Formative Assessment

During lectures, the Personal Response System and/or other ways of student interaction will be used for formative assessment.

Feedback

Formative feedback for in-course assessments will be provided in written form. Additionally, formative feedback on performance will be provided informally during practical sessions.
