Let S be a set of n line segments in the plane. The excess of S is the number of repetitions of segments of S along the boundary of the same face of A(S), summed over all segments and faces. We show t...

We address the task of an efficient implementation of Prolog extensions. Prolog is a very good language for prototyping and almost any extension can be quickly written in Prolog using a Prolog interpr...
We consider a scenario where a client communicates with a database server by posing boolean conjunctive queries, or more generally, counts of conjunctive queries. We investigate to what extent feature...
