A logic program strongly quasi-terminates when only a finite number of distinct atoms (modulo variable renaming) are derivable from any given query and computation rule. This noti...
Abstract. We consider the problem of whether a given preferred answer set program can be reduced to a propositional formula. Research on this topic is of both theoretical and pract...
Abstract. We propose a general framework for assertion-based debugging of constraint logic programs. Assertions are linguistic constructions which allow expressing properties of pr...
Similarity-based Logic Programming (briefly, SLP) has been proposed to enhance the LP paradigm with a kind of approximate reasoning which supports flexible information retrieval a...
We present a declarative debugger for lazy functional logic programs with polymorphic type discipline. Whenever a computed answer is considered wrong by the user (error symptom), ...
