A Faster Counterexample Minimization Algorithm Based on Refutation Analysis
It is a hot research topic to eliminate irrelevant variables from counterexample, to make it easier to be understood. The BFL algorithm is the most effective counterexample minimi...

Distinguishing SAT from Polynomial-Size Circuits, through Black-Box Queries
We may believe SAT does not have small Boolean circuits. But is it possible that some language with small circuits looks indistiguishable from SAT to every polynomialtime bounded ...

Extending SAT Solvers to Cryptographic Problems
Cryptography ensures the confidentiality and authenticity of information but often relies on unproven assumptions. SAT solvers are a powerful tool to test the hardness of certain ...

Encoding Quantified CSPs as Quantified Boolean Formulae
Quantified Constraint Satisfaction Problems (QCSPs) are CSPs in which some variables are universally quantified. For each possible value of such variables, we have to find ways to ...
