Abstract. Most software is developed using interactive computing systems and substantial compute-power. Considerable assistance can be given to the developer by providing language-...
The "nearest neighbor" relation, or more generally the "k nearest neighbors" relation, defined for a set of points in a metric space, has found many uses in co...
Bad error handling is the cause of many service outages. We address this problem by a novel approach to detect and patch bad error handling automatically. Our approach uses error ...
We address the verification of programmable logic controllers (PLC). In our approach, a PLC program is translated into a special type of colored Petri net, a so-called register net...
In order to deal efficiently with infinite regular trees (or other pointed graph structures), we give new algorithms to store such structures. The trees are stored in such a way th...
