Gregor Leusch :: Chair of Computer Science 6

During the Summer term of 2006, my colleagures Christian Plahl, Daniel Stein, and I have taken care of the lecture Data Structures and Algorithms for CS students in the second semester. It was great fun to work with such a bunch of bright students (and colleagues), thank you all for participating!

Software

During the last couple of years, I have developed -- and am still developing -- EvalTrans, a software package for the manual and automatic evaluation of Machine Translation.
