More on Unfold/Fold Transformations of Normal Programs: Preservation of Fitting's Semantics
The unfold/fold transformation system defined by Tamaki and Sato was meant for definite programs. It transforms a program into an equivalent one in the sense of both the least tter...

A Default Approach to Semantics of Logic Programs with Constraint Atoms
We define the semantics of logic programs with (abstract) constraint atoms in a way closely tied to default logic. Like default logic, formulas in rules are evaluated using the cl...
