Abstract In this paper we study a variation of the random $k$ -SAT problem, called polarised -SAT, which contains both classical model and version monotone another well-known NP-complete SAT. there is polarisation parameter $p$ , in half clauses each variable occurs negated with probability pure otherwise, while other probabilities are interchanged. For $p=1/2$ get model, at extreme have fully ...

A serological survey was conducted in apparently healthy, unvaccinated indigenous Tswana goats and sheep in Kasane, Maun and Shakawe districts in northwestern Botswana in order to determine in these animals, the levels of exposure to the South African Territories (SAT) serotypes: SAT 1, SAT 2 and SAT 3 of foot-and-mouth disease virus (FMDV). A total of 250, 142 and 134 goat sera originating res...

Max-SAT is the problem of finding an assignment minimizing the number of unsatisfied clauses in a CNF formula. We propose a resolution-like calculus for Max-SAT and prove its soundness and completeness. We also prove the completeness of some refinements of this calculus. From the completeness proof we derive an exact algorithm for Max-SAT and a time upper bound. We also define a weighted Max-SA...

Contemporary satisfiability solvers are the corner-stone of many successful applications in domains such as automated verification and artificial intelligence. The impressive advances of SAT solvers, achieved by clever engineering and sophisticated algorithms, enable us to tackle Boolean Satisfiability (SAT) problem instances with millions of variables – which was previously conceived as a hope...

is satisfiable is one of the most fundamental problems in computer science, known as the canonical NP-complete Boolean satisfiability (SAT) problem (Biere et al. 2009). In addition to its theoretical importance, major advances in the development of robust implementations of decision procedures for SAT, SAT solvers, have established SAT as an important declarative approach for attacking various ...

The 45S and 5S rDNA loci were physically mapped by double-probe FISH on mitotic metaphase chromosomes in the six strains of F. esculentum tataricum. Results showed that tataricum very small similar. diploid karyotype formulas these two species 2n=2x=16=12m+4m (SAT) 2n=2x=16=12m+4sm (SAT), respectively. Four pairs IS, IIS, IIIL, VL, as well IL IVS esculentum, five VIIS, three IL, IVS, VIS There ...

There is little evidence showing the relationship between the Scholastic Assessment Test (SAT) and g (general intelligence). This research established the relationship between SAT and g, as well as the appropriateness of the SAT as a measure of g, and examined the SAT as a premorbid measure of intelligence. In Study 1, we used the National Longitudinal Survey of Youth 1979. Measures of g were e...

The satissability (SAT) problem is a core problem in mathematical logic and computing theory. In practice, SAT is fundamental in solving many problems in automated reasoning, computer-aided design, computer-aided manufacturing, machine vision, database, robotics, integrated circuit design, computer architecture design, and computer network design. Traditional methods treat SAT as a discrete, co...

In this technical report we summarize the evolution of SAT solvers implemented at the formal methods group at ETH Zürich. We start with LIMMAT and COMPSAT, which both took part in the SAT’03 SAT solver competition. From the more ambitious design of FUNEX we reach the minimal implementation of NANOSAT. We close the discussion with an overview on how our QBF solver QUANTOR can be used as a prepro...
