We present an algorithm to solve XPath decision problems under regular tree type constraints and show its use to statically typecheck XPath queries. To this end, we prove the deci...
We describe a working multi-agent architecture based on Defeasible Logic Programming (DeLP) by Garc´ıa and Simari where agents are engaged in an argumentation to reach a common c...
Abstract. We present a novel counterexample generator for the interactive theorem prover Isabelle based on a compiler that synthesizes test data generators for functional programmi...
Abstract. Ordered Choice Logic Programming (OCLP) allows for preferencebased decision-making with multiple alternatives without the burden of any form of negation. This complete ab...
We assume that safety of information stored in a database depends on the reliability of the agents who have performed the insertions in the database. We present a logic S to repres...
