##### Abstract

The course is an introduction to discrete mathematics as a foundation to work within the fields of computer science, information technologies, and software development.##### Description

Mathematics and logic are our key tools for both understanding computers and for modelling the world around us. Abstractions from mathematics pervade computer science, and to truly excel at both programming computers and model aspects of the real world in computers, one must understand the core vocabulary of mathematics provided in this course.

The course aims at providing the basics of the mathematical foundations of computer science.

The course develops the necessary terminology and conceptual tools needed for later courses. This includes:

- formal reasoning, induction, set theory, relations and functions
- models of computation, such as finite state machines and grammars
- basic graph theory, language theory
- combinatorics, probability and number theory

Central terms and concepts: Logic, specifications, sets and sequences, functions, sums, induction and recursion, number theory, permutations and combinations, discrete probability, relations, graphs, trees, finite state machines, grammars and theory of computation.

##### Formal prerequisites

Basic arithmetic.Please note that this course is not open to bachelor-students. Instead bachelor students can take the SWU Bachelor course: Foundations of Computing - Discrete Mathematics BSc.

##### Intended learning outcomes

After the course, the student should be able to:

- Describe and apply formal definitions
- Conduct and explain basic formal proofs
- Work with regular languages and finite state machines
- Use models of computation and specification
- Use combinatorial reasoning
- Assess probabilities of events
- Use basic modular arithmetic

##### Learning activities

The course consists of 14 weeks of lectures and exercises.

- The lectures will provide the theory and examples of formal definitions, formal proofs, regular languages, state machines, models of computations, combinatorics, discrete probabilities and modular arithmetic (c.f. ILO).
- The weekly exercises are written exercises that train the students in working with and apply the theory introduced in the lectures. The problems that the students solve in the weekly exercises will prepare the students for the written exam, as the exam will contain problems of similar nature.

##### Mandatory activities

There are six mandatory assignments that have to be handed in though a peer-grading system. For each assignment it is mandatory that the student gives peer-feedback at a satisfactory level.The student will receive the grade NA (not approved) at the ordinary exam, if the mandatory activities are not approved and the student will use an exam attempt.

- Exam with preparation: 20%

##### Ordinary exam

**Exam type:**

C: Submission of written work, External (7-point scale)

**Exam variation:**

C22: Submission of written work – Take home

**Exam submission description:**

4 hour 15 minute LearnIT Quiz.

Aids allowed: Calculator, textbook, lecture notes

No communication and collaboration allowed.

Random fraud control with Zoom will be conducted right after the submission.

Student Affairs and Programmes will randomly select 20 % of students who will have to show up in Zoom to check authorship of submitted solutions. The selection of students for fraud control will be published in LearnIT right after the exam together with a link to the Zoom meeting.
