ASTERYX : A model-Agnostic SaT-basEd appRoach for sYmbolic and score-based eXplanations

Ryma Boumazouza, Fahima Cheikh-Alili, Bertrand Mazure +1

The ever increasing complexity of machine learning techniques used more and more in practice, gives rise to the need to explain the predictions and decisions of these models, often…

Rectifying Mono-Label Boolean Classifiers

Sylvie Coste-Marquis, Pierre Marquis

We elaborate on the notion of rectification of a Boolean classifier . Given and some background knowledge , postulates characterizing the way must be changed into a n…

Generalized binary utility functions and fair allocations

Franklin Camacho, Rigoberto Fonseca-Delgado, Ramón Pino Pérez +1

The problem of finding envy-free allocations of indivisible goods can not always be solved; therefore, it is common to study some relaxations such as envy-free up to one good (EF1)…

Constant-Delay Enumeration for Nondeterministic Document Spanners

Antoine Amarilli, Pierre Bourhis, Stefan Mengel +1

We consider the information extraction framework known as document spanners, and study the problem of efficiently computing the results of the extraction from an input document, wh…

Graph Width Measures for CNF-Encodings with Auxiliary Variables

Stefan Mengel, Romain Wallon

We consider bounded width CNF-formulas where the width is measured by popular graph width measures on graphs associated to CNF-formulas. Such restricted graph classes, in particula…

Enumeration on Trees with Tractable Combined Complexity and Efficient Updates

Antoine Amarilli, Pierre Bourhis, Stefan Mengel +1

We give an algorithm to enumerate the results on trees of monadic second-order (MSO) queries represented by nondeterministic tree automata. After linear time preprocessing (in the…

Nopol: Automatic Repair of Conditional Statement Bugs in Java Programs

Jifeng Xuan, Matias Martinez, Favio Demarco +5

We propose NOPOL, an approach to automatic repair of buggy conditional statements (i.e., if-then-else statements). This approach takes a buggy program as well as a test suite as in…

On Rational Entailment for Propositional Typicality Logic

Richard Booth, Giovanni Casini, Thomas Meyer +1

Propositional Typicality Logic (PTL) is a recently proposed logic, obtained by enriching classical propositional logic with a typicality operator capturing the most typical (alias…

Knowledge Compilation, Width and Quantification

Florent Capelli, Stefan Mengel

We generalize many results concerning the tractability of SAT and #SAT on bounded treewidth CNF-formula in the context of Quantified Boolean Formulas (QBF). To this end, we start b…

QBF as an Alternative to Courcelle's Theorem

Michael Lampis, Stefan Mengel, Valia Mitsou

We propose reductions to quantified Boolean formulas (QBF) as a new approach to showing fixed-parameter linear algorithms for problems parameterized by treewidth. We demonstrate th…

Enumeration on Trees under Relabelings

Antoine Amarilli, Pierre Bourhis, Stefan Mengel

We study how to evaluate MSO queries with free variables on trees, within the framework of enumeration algorithms. Previous work has shown how to enumerate answers with linear-time…

A Circuit-Based Approach to Efficient Enumeration

Antoine Amarilli, Pierre Bourhis, Louis Jachiet +1

We study the problem of enumerating the satisfying valuations of a circuit while bounding the delay, i.e., the time needed to compute each successive valuation. We focus on the cla…

XCSP3: An Integrated Format for Benchmarking Combinatorial Constrained Problems

Frederic Boussemart, Christophe Lecoutre, Gilles Audemard +1

We propose a major revision of the format XCSP 2.1, called XCSP3, to build integrated representations of combinatorial constrained problems. This new format is able to deal with mo…

Parameterized Compilation Lower Bounds for Restricted CNF-formulas

Stefan Mengel

We show unconditional parameterized lower bounds in the area of knowledge compilation, more specifically on the size of circuits in decomposable negation normal form (DNNF) that en…

Compact-Table: Efficiently Filtering Table Constraints with Reversible Sparse Bit-Sets

Jordan Demeulenaere, Renaud Hartert, Christophe Lecoutre +4

In this paper, we describe Compact-Table (CT), a bitwise algorithm to enforce Generalized Arc Consistency (GAC) on table con- straints. Although this algorithm is the default propa…

Agenda Separability in Judgment Aggregation

Jérôme Lang, Marija Slavkovik, Srdjan Vesic

One of the better studied properties for operators in judgment aggregation is independence, which essentially dictates that the collective judgment on one issue should not depend o…

A Comparative Study of Ranking-based Semantics for Abstract Argumentation

Elise Bonzon, Jérôme Delobelle, Sébastien Konieczny +1

Argumentation is a process of evaluating and comparing a set of arguments. A way to compare them consists in using a ranking-based semantics which rank-order arguments from the mos…

Counting Answers to Existential Positive Queries: A Complexity Classification

Hubie Chen, Stefan Mengel

Existential positive formulas form a fragment of first-order logic that includes and is semantically equivalent to unions of conjunctive queries, one of the most important and well…

Minimal Distance of Propositional Models

Mike Behrisch, Miki Hermann, Stefan Mengel +1

We investigate the complexity of three optimization problems in Boolean propositional logic related to information theory: Given a conjunctive formula over a set of relations, find…

A partial taxonomy of judgment aggregation rules, and their properties

Jerôme Lang, Gabriella Pigozzi, Marija Slavkovik +2

The literature on judgment aggregation is moving from studying impossibility results regarding aggregation rules towards studying specific judgment aggregation rules. Here we give…

The Logic of Counting Query Answers

Hubie Chen, Stefan Mengel

We consider the problem of counting the number of answers to a first-order formula on a finite structure. We present and study an extension of first-order logic in which algorithms…

Identifying the Class of Maxi-Consistent Operators in Argumentation

Srdjan Vesic

Dung's abstract argumentation theory can be seen as a general framework for non-monotonic reasoning. An important question is then: what is the class of logics that can be subsumed…

Second-Order Consistencies

Christophe Lecoutre, Stephane Cardon, Julien Vion

In this paper, we propose a comprehensive study of second-order consistencies (i.e., consistencies identifying inconsistent pairs of values) for constraint satisfaction. We build a…
