Logic and Discrete Mathematics (Spring 2020)

See the course description at study.ruc.dk for a brief and formal description of the course. Practical information can be found at the Moodle page of the course (requires login). All day-to-day information will be sent via Moodle to your RUC email account, so please read your RUC email regularly.

 

This page describes the content and structure of the course. In the following, the main subjects of the course are described; a detailed description of the structure of the course can be found further down the page.

·        Logic The first subject of the course is logic, that is, propositional- and predicate logic as well as rules of inference and logic in mathematical proofs. This part of the course comprises the first six course days and covers the first chapter of the textbook.

·        Sets and functions Two course days cover sections 2.1 - 2.3 in the book, which concern sets, set operations (union, intersection, powerset, Cartesian product, ...) and functions between sets (injections, surjections, inverse functions, ...). This is mainly high school material, formulated more rigeously.

·        Algorithms and complexity Three course days covers sections 3.1 - 3.3 as well as Appendix A-3, which concern algorithms, pseudocode, and the computational complexity of algorithms.

·        Induction and recursion Two course days cover sections 4.1 - 4.4 in the book, which concern mathematical induction, structural induction, recursive definitions, and recursive algorithms. The principle of mathematical induction can be used to prove a tremendous variety of mathematical results. Understanding how to read and construct proofs by mathematical induction is a key goal of this part of the course.

·        Modeling computation Two course days covers sections 12.1 and 12.5 in the book. Section 12.1 concerns formal languages and different types of grammars, providing models for both natural languages, such as English, and for programming languages, such as Java. Section 12.5 concerns Turing machines, which are general mathematical models of computers, invented by the British mathematician Alan Turing.

During the course three mini projects are carried out, based on a handed out problem formulation. One of the mini-projects may optionally involve use of the programming language Prolog (Programming in logic), which will be briefly introduced at the course.
