Realization of c-Inference as a SAT Problem
Semantically based on Spohn’s ranking functions, c-representations are special ranking models obtained by assigning individual integer impacts to the conditionals in a knowledge base R and by defining the rank of each possible world as the sum of the ...

Local Consistency and SAT-Solvers [PDF]
Local consistency techniques such as k-consistency are a key component of specialised solvers for constraint satisfaction problems. In this paper we show that the power of using k-consistency techniques on a constraint satisfaction problem is precisely captured by using a particular inference rule, which we call negative-hyper-resolution, on the ...

A Verified Implementation of the DPLL Algorithm in Dafny
We present a DPLL SAT solver, which we call TrueSAT, developed in the verification-enabled programming language Dafny. We have fully verified the functional correctness of our solver by constructing machine-checked proofs of its soundness, completeness ...

Boosting the Performance of CDCL-Based SAT Solvers by Exploiting Backbones and Backdoors
Boolean structural measures were introduced to explain the high performance of conflict-driven clause-learning (CDCL) SAT solvers on industrial SAT instances.

Optimal SAT Solver Synthesis of Quantum Circuits Representing Cryptographic Nonlinear Functions [PDF]
In this article we present a procedure that allows to synthesize optimal circuit representing any reversible function within reasonable size limits. The procedure allows to choose either the NCT or the MCT gate set and specify any number of ancillary ...

Branching Heuristic Strategy Based on Learnt Clauses Deletion Strategy for SAT Solver [PDF]
For the SAT solver,most popular branch variable decision-making strategies are based on the variable activity evaluation of conflict.The unassigned variable with the maximum activity is selected as the decision variable,and the most recent conflict is ...

Model Abstraction for Discrete-Event Systems Using a SAT Solver
Model abstraction for finite state automata is beneficial to reduce the complexity of discrete-event systems (DES), enhance the readability and facilitate the control synthesis and verification of DES.

Applying aspiration in local search for satisfiability.
The Boolean Satisfiability problem (SAT) is a prototypical NP-complete problem, which has been widely studied due to its significant importance in both theory and applications.

Incremental SAT Library Integration Using Abstract Stobjs [PDF]
We describe an effort to soundly use off-the-shelf incremental SAT solvers within ACL2 by modeling the behavior of a SAT solver library as an abstract stobj. The interface allows ACL2 programs to use incremental SAT solvers, and the abstract stobj model
