2011 is almost over and more than 9 months of my PhD have already passed by. During my math diploma I was founded by the german national academic foundation. Besides some really nice benefits that came along with this every 6 months I was forced to write reports about my study progress. Even though theses …

balanced binary search trees exercise for algorithms and data structures class
I created some exercises regarding binary search trees. This time there is no coding involved. My experience from teaching former classes is that many people have a hard time understanding why trees are usefull and what the dangers of these trees is. Therefor I have created some straight forward exercises that nevertheless involve some work …

3 exercises for Sorting problems (Quicksort , Mergesort) in Algorithms and data structures class
#1: Sorting huge files Sorting big files might not be as simple as just implementing an sort algorithm. As soon as the file does not fit in memory any more smarter implementations have to be applied. One way is to sort the file on the hard disk. We remark that not every algorithm is easily …

Despite this fact it is also important to understand the fundamental principle behind it. Unfortunately the algorithm is tought so early and the algorithm is so simple that beginning students sometimes have a hard time to understand the abstract principle behind it. Also many …
11 lessons learnt after my first scientific paper was submitted
During the last month my blog was rather quite. I dicided that I was aiming to submit my first paper to a top conference with a deadline of november first. Well besides the fact that I almost forgot about the fact that I also have a private life – as well as my collegues helping …
