We present a sound and complete proof technique, based on syntactic logical relations, for showing contextual equivalence of expressions in a -calculus with recursive types and imp...
The eplex library of the ECLi PSe Constraint Logic Programming platform allows the integration of Mathematical Programming techniques with its native Constraint Logic Programming t...
Abstract. We define a translation of aggregate programs to normal logic programs which preserves the set of partial stable models. We then define the classes of definite and str...
The paper focusses on the logical backgrounds of the Dijkstra-Scholten program development style for correct programs. For proving the correctness of a program (i.e. the fact that...
This work is a contribution to prioritized reasoning in logic programming in the presence of preference relations involving atoms. The technique, providing a new interpretation fo...
