I was interviewed by a regional newspaper ("Salzburger Nachrichten") at the end of last year: https://www.pressreader.com/austria/salzburger-nachrichten/20191227/page/25
The article was illustrated with a visualization where I was overlaying the photograph of a street network with its corresponding graph in tikz. Thanks to Clemens Koppensteiner whose onimage.sty makes drawing on an image really easy!
I've signed the self-commitment to not take short-haul business flights. #ScientistsForFuture
My student Matthias Reichinger finished his bachelor thesis titled "Ranking Job Opportunities in a Personalised Career Recommendation System". For me, it was a nice experience to get in touch again with some applied Data Science and Machine Learning techniques.
Congratulations for graduating, Matthias!
Today at lunch, I've learned about the Trash Compaction problem: Can you push objects on a grid into the compact shape of a rectangle if you're only allowed to push all objects from one side simultaneously. Akitaya, Aloupis, Löffler, and Rounds showed that the problem is NP-complete.
The fun variant of this problem talks about pushing around coconuts with a giant coconut pusher... Here are some neat slides: http://www.staff.science.uu.nl/~loffl001/publications/slides/trash_compaction.pdf
