"Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better." - E. W. Dijkstra
Members of our department are focused on
the more foundational aspects of Theoretical Computer Science and their
work can be classified into three main areas: Combinatorics,
Computational Complexity, and Mathematical Logic. In all these
areas, we strive not only to achieve new results but to broaden the
repertoire of approaches that are considered standard. In particular we
pursue three main aims:
Combinatorics: to study the
recent challenging problems of extremal graph theory and discrete random
structures, and thus contribute to these central topics in combinatorics
which are crucial e.g. for our understanding of very large networks.
Computational Complexity: to
deepen our knowledge of relations among complexity classes via standard
and non-standard computational models considering both the usual
complexity measures like time or space and new ones relevant in
neurocomputing and knowledge compilation.
MathematicalLogic: to
develop and apply non-classical logics for reasoning, in both natural
and artificial scenarios, with real-life information, which is often
uncertain, graded, or even contradictory, and changing over time.
