Minimal unsatisfiability and autarkies
H Kleine Büning, O Kullmann - Handbook of Satisfiability, 2009 - ebooks.iospress.nl
Minimal unsatisfiability describes the reduced kernel of unsatisfiable formulas. The
investigation of this property is very helpful in understanding the reasons for unsatisfiability …

Learning the boundary of inductive invariants
We study the complexity of invariant inference and its connections to exact concept learning.
We define a condition on invariants and their geometry, called the fence condition, which …

Prime forms and minimal change in propositional belief bases
J Marchi, G Bittencourt, L Perrussel - Annals of Mathematics and Artificial …, 2010 - Springer
This paper proposes to use prime implicants and prime implicates normal forms to represent
belief sets. This representation is used, on the one hand, to define syntactical versions of …

Constraint satisfaction problems in clausal form II: Minimal unsatisfiability and conflict structure
O Kullmann - Fundamenta Informaticae, 2011 - content.iospress.com
Concluding this mini-series of 2 articles on the foundations of generalised clause-sets, we
study the combinatorial properties of non-boolean conjunctive normal forms (clause-sets) …

Constraint satisfaction problems in clausal form I: Autarkies and deficiency
O Kullmann - Fundamenta Informaticae, 2011 - content.iospress.com
We consider the problem of generalising boolean formulas in conjunctive normal form by
allowing non-boolean variables, with the goal of maintaining combinatorial properties …

Learning Boolean Functions with Queries.
The objective of machine learning is to acquire knowledge from available information in an
automated manner. As an example, one can think of obtaining rules for medical diagnosis …

Towards a theory of good SAT representations
M Gwynne, O Kullmann - arXiv preprint arXiv:1302.4421, 2013 - arxiv.org
We aim at providing a foundation of a theory of" good" SAT representations F of boolean
functions f. We argue that the hierarchy UC_k of unit-refutation complete clause-sets of level …

Trading inference effort versus size in CNF knowledge compilation
M Gwynne, O Kullmann - arXiv preprint arXiv:1310.5746, 2013 - arxiv.org
Knowledge Compilation (KC) studies compilation of boolean functions f into some formalism
F, which allows to answer all queries of a certain kind in polynomial time. Due to its …

Horn upper bounds and renaming
Selman and Kautz [22] proposed an approach to compute a Horn CNF approximation of
CNF formulas. We extend this approach and propose a new algorithm for the Horn least …
