Our verified bit blasting algorithm supports the full QF_BV logic of SMT-LIB ; it is specified and formally verified in the proof assistant Coq . We compare CoqQFBV with CVC4 , Bitwuzla , and Boolector on benchmarks from the QF_BV division of the single query track in the 2020 SMT ...
The rewriting algorithm commonly used by modern SMT solvers iteratively applies a set of ad ho... A Nadel - Springer International Publishing 被引量: 10发表: 2014年 Fine Grained SMT Proofs for the Theory ofFixed-Width Bit-Vectors Summary: Many high-level verification tools rely on SMT solvers...
This paper develops a back-translation algorithm showing, for the first time, how back-translation can be universally applied, whatever the LIA interpolant. This avoids the need for deriving a BV interpolant by bit-blasting the BV formulae, as a backup process when back-translation fails. The ...
Basically, a trained data-driven algorithm allows a computer to identify when the bit touches a shale-rich part of the formation by a continuous screening through the real-time Measurements While Drilling (MWD) data. In machine learning, this problem is referred as the two-class classification ...
Compared to drilling and blasting, mechanical excavation provides an important potential for high advance rates, reduced costs, smaller capital expenditure, improved strata control and a safer working environment. Consequently, in both mining and civil engineering projects, an increasing amount of rock ex...
focus inSelfie focusmode, much like the bokeh effect on the Google Pixel 2 and Pixel 2XL. It’s accomplished entirely in software, and the results aren’t perfect — several of our test selfies, the outer edges of the subject’s face are a bit smudged where the algorithm blended the ...
Our experiments demonstrate that our algorithm outperforms alternative quantifier elimination techniques based on bit-blasting and Omega Test. We also extend this algorithm to work with Boolean combinations of LMEs, LMDs and LMIs.Ajith K. John
The procedure is embedded in a congruence closure algorithm, whose data structures are extended in order to efficiently manage the relations between bit-vector slicings, modulo equivalence classes. The resulting procedure is incremental, backtrack-able, and proof producing: it can be used as a ...
Bit-Vector Model Counting Using Statistical Estimation 135 We implement our algorithm in a tool SearchMC that wraps either a bit- vector SMT solver compatible with the SMT-LIB 2 standard or a SAT solver, and report experimental results. SearchMC can be used to count solutions with respect to...
