The "Foundations" cluster is dedicated to the fundamental aspects of complex IT systems. The focus is on understanding formal models as abstractions and tools, as well as on the development and analysis of efficient algorithms and processes in various domains.

Our Mission

Our mission is to create the fundamentals upon which further research within various disciplines can build. We are particularly interested in understanding complex systems and relevant computational problems.

Research Focuses

  1. Formal models: Formal models play a central role in the "Foundations" cluster. These models help us to precisely describe complex IT systems and analyze their functionality and performance.
     
  2. Algorithmics: Algorithms and processes are developed and analyzed using mathematical methods. Probabilistic aspects are also considered. The aim is to develop efficient algorithms, also for complex problems, and to improve our understanding of problem complexity.
