Exploiting Cycle Structures in Max-SAT
We investigate the role of cycles structures (i.e., subsets of clauses of the form ¯l1 ∨ l2, ¯l1 ∨ l3, ¯l2 ∨ ¯l3) in the quality of the lower bound (LB) of modern MaxSAT ...

Resolution cannot polynomially simulate compressed-BFS
Many algorithms for Boolean satisfiability (SAT) work within the framework of resolution as a proof system, and thus on unsatisfiable instances they can be viewed as attempting to...

Regular Encodings from Max-CSP into Partial Max-SAT
We define a number of original encodings, called regular encodings, that map Max-CSP instances into Partial MaxSAT instances. First, we obtain new direct and (minimal) support en...
