Brief Description

The module aims to cover both classical and non-classical logics focusing on their deductive and algorithmic aspects. It introduces mathematical logic as a means for specifying, verifying and reasoning about computer programs. Its emphasis, in contrast to other similar logic modules, is on how logic can be used to represent computational problems, how these representations can be proved correct and how they can be executed on a computer. Topics covered include classical logic theories, modal logic, program specfication and verification and typing.

Attendance of labs: Lab attendance is mandatory. You are allowed to miss one of the 11 labs. Any missed lab beyond one leads to a deduction of 1% of the overall assessment (in addition to possibly missing a quiz). Coming late for more than 10 minutes is considered missing the lab. You are allowed to leave early, in those lab sessions that end in a quiz.
