Conjunctive Query Answering for the Description Logic SHIQ
Conjunctive queries play an important role as an expressive query language for Description Logics (DLs). Although modern DLs usually provide for transitive roles, conjunctive quer...

Merging Logic Programs under Answer Set Semantics
This paper considers a semantic approach for merging logic programs under answer set semantics. Given logic programs P1, . . . , Pn, the goal is to provide characterisations of the...

Logics with Rank Operators
—We introduce extensions of first-order logic (FO) and fixed-point logic (FP) with operators that compute the rank of a definable matrix. These operators are generalizations o...

Optimal Tableaux for Conditional Logics with Cautious Monotonicity
Conditional logics capture default entailment in a modal framework in which non-monotonic implication is a first-class citizen, and in particular can be negated and nested. There i...

Application of Constraint Logic Programming for VLSI CAD Tools
Abstract: This paper describes the application of CLP (constraint logic programming) to several digital circuit design problems. It is shown that logic programming together with ef...
