Module summary

Logic is the study of reasoning itself. Since its origins in ancient Greece, logic has evolved into a wide and vibrant subject, with many important applications to other areas of mathematics and to computer science. A typical application in mathematics is to decide whether a certain statement can be proved from a given set of axioms (e.g. whether the axiom on parallel lines follows from Euclid’s other axioms). In computer science, ever since the pioneering work of Turing, logic has played a fundamental role in describing and analysing algorithms. The module will provide an introduction to logic, with emphasis on its computational applications.

Objectives

On completion of this module, students should be able...
1. To describe the fundamental notions of mathematical logic, including the distinction between syntax and semantics.
2. To present a proof of the completeness theorem in the propositional case and introduce a first order predicate calculus.
3. To describe the fundamental notions of Computational Logic, including algorithmic proof verification.

Learning outcomes

1. To express logical arguments in a formal language and thereby to analyse their correctness.
2. To distinguish between syntax and semantics, and give simple formal proofs in a natural deduction system.
3. To give a proof by induction on a finite tree.
4. To apply the soundness and completeness theorems to establish whether a formula is derivable from a set of axioms or not.
5. To understand the working of fundamental algorithms in computational logic.

Methods of Assessment

Coursework
Assessment type Notes % of formal assessment
Computer Exercise . 30
In-course Assessment . 10
Total percentage (Assessment Coursework) 40

In order to pass the module, students must pass the MATH2041 component (which is at least 40% on exam and in-course assessment combined) and score at least 40% on the Computer Exercises.

Exams
Exam type Exam duration % of formal assessment
Open Book exam 2.0 Hrs 0 Mins 60
Total percentage (Assessment Exams) 60

Students who have failed the MATH2041 component will need to resit the exam; students who have failed the computer exercises will need to resubmit these. There is no resit available for the 10% in-course assessment component of this module. If the module is failed, the mark for this component will be carried forward and added to the resit exam and/or computer exercises mark with the same weighting as listed above.
