A.: Resolution-based certificate extraction for QBF (tool presentation

by Aina Niemetz, Mathias Preiner, Florian Lonsing, Martina Seidl, Armin Biere - In: Proc. SAT’12 , 2012
"... Abstract. A certificate of (un)satisfiability for a quantified Boolean formula (QBF) represents concrete assignments to the variables, which act as witnesses for its truth value. Certificates are highly requested for practical applications of QBF like formal verification and model checking. We prese ..."

present an integrated set of tools realizing resolution-based certificate extraction for QBF in prenex conjunctive normal form. Starting from resolution proofs produced by the solver DepQBF, we describe the workflow consisting of proof checking, certificate extraction, and certificate checking. We

Efficient Extraction of QBF (Counter)models from Long-Distance Resolution Proofs

by Valeriy Balabanov, Jie-hong R. Jiang, Mikoláš Janota, Magdalena Widl
"... Many computer science problems can be naturally and compactly expressed using quantified Boolean formu-las (QBFs). Evaluating the truth or falsity of a QBF is an important task, and constructing the correspond-ing model or countermodel can be as important and sometimes even more useful in practice. ..."
Abstract - Add to MetaCart
. Modern search and learning based QBF solvers rely fundamentally on resolution and can be instrumented to produce resolu-tion proofs, from which in turn Skolem-function models and Herbrand-function countermodels can be extracted. These (counter)models are the key enabler of various applications. Not until

Long-Distance Resolution: Proof Generation and Strategy Extraction in Search-Based QBF Solving

by Uwe Egly, Florian Lonsing, Magdalena Widl , 2013
"... Strategies (and certificates) for quantified Boolean formulas (QBFs) are of high practical relevance as they facilitate the verification of results returned by QBF solvers and the generation of solutions to problems formulated as QBFs. State of the art approaches to obtain strategies require traver ..."

As a practical application, we consider search-based QBF solvers which are able to learn tautological clauses based

"... We present the experimental reconstruction of sub-wavelength features from the far-field of sparse optical objects. We show that it is sufficient to know that the object is sparse, and only that, and recover 100 nm features with the resolution of 30 nm, for an illuminating wavelength of =532 nm. Our ..."

1A Sub-Nyquist Radar Prototype: Hardware and Algorithms

by Eliahu Baransky, Gal Itzhak, Idan Shmuel, Noam Wagner, Eli Shoshan, Yonina C. Eldar
"... Abstract—Traditional radar sensing typically employs matched filtering between the received signal and the shape of the transmitted pulse. Matched filtering is conventionally carried out digitally, after sampling the received analog signals. Here, principles from classic sampling theory are generall ..."
