Learning to satisfy

2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
This paper investigates a class of learning problems called learning satisfiability (LSAT) problems, where the goal is to learn a set in the input (feature) space that satisfies a number of desired output (label/response) constraints. LSAT problems naturally arise in many applications in which one is interested in the class of inputs that produce ...

Sums of Squares, Satisfiability and Maximum Satisfiability

2005
Recently the Mathematical Programming community showed a renewed interest in Hilbert's Positivstellensatz. The reason for this is that global optimization of polynomials in ℝ[x1,...,xn] is $\mathcal{NP}$-hard, while the question whether a polynomial can be written as a sum of squares has tractable aspects.

On the satisfiability of circumscription

Artificial Intelligence, 1986
Es wird gezeigt: Wenn A erfüllbar ist und fast universal bezüglich P, so ist Circum(A;P) erfüllbar. Wenn A universal und erfüllbar ist, so ist Circum(A;P;Q) erfüllbar. Für disjunkte \(P^ 1,...,P^ k\), Q und jedes universale, erfüllbare A ist Circum(A,\(P^ 1>...>P^ k,Q)\) erfüllbar.

Approximating satisfiable satisfiability problems

1997
We study the approximability of the Maximum Satisfiability Problem (MAX SAT) and of the boolean k-ary Constraint Satisfaction Problem (MAX kCSP) restricted to satisfiable instances. For both problems we improve on the performance ratios of known algorithms for the unrestricted case.

Satisfiability and Theories

2009 11th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2009
We give a simple introduction to satisfiability modulo theories intended fornon-specialists. No previous background is assumed.

Hypergraph satisfiability

Reports Math. Log., 2021
Summary: A notion of satisfiability is defined for collections of vertex sets of a hypergraph and a method for determining satisfiability, called resolution, is introduced. An important special case is the resolution technique for determining satisfiability of a set of clauses in propositional logic.
