Nowadays everything has to be evaluated as “objectively” as possible.

In many surveys on computer science, aspects of theoretical computer science are no longer mentioned. Therefore we have carried out a research ranking of German universities with regard to classical theoretical computer science. So this table was created in November 2011 and can be read:


  1. In our opinion, the classic areas of theoretical computer science are:
    a) Complexity theory, b) Formal languages, c) Algorithm theory.
  2. At each university it was checked whether these areas were represented (some universities are therefore excluded from the evaluation).
  3. In November 2011, the h-index and the g-index were determined for the holder of the respective professorship using an “h-index calculator”. Other tools may provide different numbers.
  4. If several professorships were to conduct theoretical computer science (at large universities), then for reasons of comparability the professorship was identified/used that comes closest to theoretical computer science in Trier in terms of content.
  5. The obtained lists were sorted first by h-Index andy secondarily by g-Index.


According to this survey, Theoretical Computer Science at the University of Trier ranks among the top twenty German universities and is therefore in the top third of the table. Like many things, these numbers cannot be seen in absolute terms; the differences are (as you can see) often marginal, but certainly reflect a trend.


In contrast to some other ranking methods, locations with numerous professorships and employees are not given preference, as only work in which the head of the institute was involved is counted. This procedure makes sense in theoretical computer science insofar as the professional culture dictates that institute directors are not automatically represented in the list of authors, as long as only the institute is primarily involved in the publication.
