NDAB16011U Logic in Computer Science (LICS)
The aim of this course is to provide a firm theoretical
foundation of formal logic, with an emphasis on logics, properties,
techniques and algorithms relevant in computer science. Building on
the students' existing knowledge of Boolean logic and
mathematical reasoning, the course includes both fundamental logic
formalisms and more specialized logics used in modelling,
specification, and verification of programs and hardware systems.
The course covers introductions to
- propositional logic,
- predicate logic,
- temporal logics LTL and CTL,
- model checking,
- binary decision diagrams, and
- formalised proving using a proof assistant.
Note that while some applications of logic will be covered in some
detail during the course, the focus of the course is primarily on
the theoretical foundations of logic in computer science rather
than its concrete applications.
At course completion, the successful student will have
Knowledge of
- Defining logics in terms of syntax, semantics and natural deduction systems, and formal reasoning about logical formulas.
- A selection of specific logics, including propositional logic, predicate logic and temporal logic (e.g. LTL and CTL).
- Fundamental properties of these logics, such as soundness, completeness and decidability.
- Algorithms for transforming logical formulas to normal forms; for deciding fundamental properties of logical formulas such as satisfiability, validity, and entailment; and (symbolic) model checking by binary decision diagrams (BDDs).
Skills in
- Deciding and proving formal properties of logical formulas (e.g. satisfiability, validity, implication and equivalence) both by semantics and natural deduction arguments.
- Proving properties relating logical inference systems and semantics, specifically soundness or completeness.
- Applying specific algorithms for deciding properties of logical formulas: SAT solvers for propositional calculus; model checking LTL/CTL; using BDDs to represent Boolean functions and perform symbolic model checking.
- Performing any of the above in the context of variants of the presented logics.
Competences to
- Use formal logic to describe real-world situations, express properties of programs and reason about them formally.
The syllabus will be posted in Absalon.

The course has been selected for ITX exam
See important information about ITX-exams at Study Information, menu point: Exams -> Exam types and rules -> Written on-site exams (ITX) - Exam registration requirements
There will be 6 weekly assignments during the course, graded on a scale from 0 to 2 points: at least 10 points are required to be qualified for the exam.
Unsatisfactorily or partially satisfactorily assignments can be resubmitted once except for the last assignment, where no resubmission is possible.
- Aid
- Written aids allowed
- Marking scale
- 7-point grading scale
- Censorship form
- No external censorship
Several internal examiners.
- Re-exam
Same as the ordinary exam.
Qualification for the re-exam requires 10 points or more from assignments, including previous solutions already handed in prior to the ordinary exam. These must be handed in no later than 3 weeks before the re-exam week.
If less than 10 students register for the re-exam, the re-exam will be a 30 minutes oral exam (including grading) after preparation (60 minutes) with written aids only (no electronic aids).
