A Max-SAT Solver with Lazy Data Structures
We present a new branch and bound algorithm for Max-SAT which incorporates original lazy data structures, a new variable selection heuristics and a lower bound of better quality. W...

Exploiting structure in symmetry detection for CNF
Instances of the Boolean satisfiability problem (SAT) arise in many areas of circuit design and verification. These instances are typically constructed from some human-designed ar...

A New Empirical Study of Weak Backdoors
Abstract. Work by Kilby, Slaney, Thiebaux and Walsh [1] showed that the backdoors and backbones of unstructured Random 3SAT instances are largely disjoint. In this work we extend t...

Improving Backtrack Search for SAT by Means of Redundancy
In this paper, a new heuristic that can be grafted to many of the most e cient branching strategies for Davis and Putnam procedures for SAT is described. This heuristic gives a hig...

Equivalence Checking Combining a Structural SAT-Solver, BDDs, and Simulation
This paper presents a verification technique for functional comparison of large combinational circuits using a novel combination of known approaches. The idea is based on a tight...
