I Don't Want to Think About it Now: Decision Theory with Costly Computation
Computation plays a major role in decision making. Even if an agent is willing to ascribe a probability to all states and a utility to all outcomes, and maximize expected utility,...

Tractable Answer-Set Programming with Weight Constraints: Bounded Treewidth Is not Enough
Cardinality constraints or, more generally, weight constraints are well recognized as an important extension of answer-set programming. Clearly, all common algorithmic tasks relat...

Diagnosis as Planning Revisited
In discrete dynamical systems change results from actions. As such, given a set of observations, diagnoses often take the form of posited events that result in the observed behavi...

Interpreting Topological Logics over Euclidean Spaces
Topological logics are a family of languages for representing and reasoning about topological data. In this paper, we consider propositional topological logics able to express the...

A Characterization of Optimality Criteria for Decision Making under Complete Ignorance
In this paper we present a model for decision making under complete ignorance. By complete ignorance it is meant that all that is known is the set of possible consequences associa...

Finding Explanations of Inconsistency in Multi-Context Systems
We provide two approaches for explaining inconsistency in multi-context systems, where decentralized and heterogeneous system parts interact via nonmonotonic bridge rules. Inconsi...

Preferential Semantics for Plausible Subsumption in Possibility Theory
Handling exceptions in a knowledge-based system has been considered as an important issue in many domains of applications, such as medical domain. In this paper, we propose severa...

Towards a Logic of Feature-Based Semantic Science Theories
The aim of semantic science is to allow for the publications of ontologies, observation data, and hypotheses/theories. Hypotheses make predictions on data and on new cases. Those ...

Walking the Decidability Line for Rules with Existential Variables
We consider positive rules in which the conclusion may contain existentially quantified variables, which makes reasoning tasks (such as Deduction) undecidable. These rules have t...
