I followed the course Computational Geometry at DIKU in the beginning of the year. For the exam, I prepared a number of exam topic dispositions.

Download PDF here

The dispositions cover the following topics:

  1. Polygon triangulation
  2. Range searching
  3. Point location
  4. Voronoi diagrams
  5. Delaunay triangulations
  6. Geometric data structures
  7. Robot motion planning and visibility graphs

The notes are primarily intended for other curious students at DIKU. If you wish to learn about the subjects, I can recommend the book Computational Geometry: Algorithms and Applications, which was used during the course.

So you’re a student at the University of Copenhagen, and you’re starting on a new course. Wouldn’t it be lovely if you could add your schedule to your calendar, so that you could keep track of when to be where?

Well, Rasmus Wriedt Larsen has devised a website, KU Calendar Helper, which automatically produces an ICAL feed you can add to your Google Calendar or similar. You can simply input the URL to the course schedule, and it’ll do the boring work for you.

To simplify this process, I created the following userscript:

To use this script, follow these simple steps:

  1. Go to the SIS-page of the course you want a calendar feed for.
  2. Click “Vis skema for kurset”
  3. On the top of the page that comes up, click “Export to calendar”
  4. Follow the instructions on the page that comes up

The script has been tested in Chrome using Tampermonkey, but should work well in Firefox using Greasemonkey as well.

A Hasse diagram generated in Mathematica.

A Hasse diagram generated in Mathematica.

It’s that time of year again; the new students have started at DIKU and start their careers as computer science students with the course DiMS — Discrete Mathematical Structures, taught from the book by the same name.

Part of the curriculum is learning about Hasse diagrams, which in essence are a way of easily visualizing the relationships between different elements under a partial order.

Now, a student came and asked me about how to draw these diagrams in Mathematica, so I got some code working which did just that. The resulting diagram, is the picture used for this post.

If you’re a student at the University of Copenhagen, you’ll probably have noticed that we recently switched to new, horrendously hard to remember usernames for logging into punkt.KU (affectionately known as license plates).

In order to better cope with change, I present to you a few tools to help make the transition smoother.

If you are a student at the University of Copenhagen, chances are that you’ve had a run-in with a service called Absalon. For the uninitiated, Absalon is based on a system called it’s learning, which is a “virtual learning environment“. As a student at KU might also know ISIS, which serves pretty much the exact same purpose.
