M.Sc. Tobias Heß

At the core of my research lies the analysis of configurable systems by means of knowledge compilation, first and foremost binary decision diagrams. Therein, my research is aimed at improving the scalability of binary decision diagrams to enable the analysis of real-world systems. Naturally, I am also interested in the concrete problems (SAT, #SAT, QBF) the analyses are composed of.
