MSc Programme in Computer Science

MSc Programme in Bioinformatics


The purpose of this course is to introduce the students to the methods for solving problems where geometrical properties are of particular importance. We will look at some basic problems; at algorithmic paradigms especially suited to solve such problems, and at geometric data structures. We will also look at the applications of computational geometry in relation to the problems of for example molecular biology. No a priori knowledge of molecular biology is required. During the course, the students will be asked to make a project proposal (7.5 or 15 ECTS) which they will have the opportunity to work on in the following block.

Computational Geometry is concerned with the design and analysis of algorithms and heuristics, exploiting the geometrical aspects of underlying problems (i.e. routing problems, network design, localization problems and intersection problems).
Applications can be found in VLSI-design, pattern recognition, image processing, operations research, statistics and molecular biology.
