In Prz91], Przymusinski introduced the partial (or 3-valued) stable model semantics which extends the (2-valued) stable model semantics dened originally by Gelfond and Lifschitz G...
We present the design and the implementation of clp(B): a boolean constraint solver inside the Constraint Logic Programming paradigm. This solver is based on local propagation meth...
We discuss a declarative characterization of inheritance in logic programming. Our approach is inspired both by existing literature on denotational models for inheritance and by e...
We describe the ucpop partial order planning algorithm which handles a subset of Pednault's ADL action representation. In particular, ucpop operates with actions that have co...
The replacement transformation operation, already defined in [28], is studied wrt normal programs. We give applicability conditions able to ensure the correctness of the operation ...
