Bounded Tree-Width and CSP-Related Problems
We study the complexity of structurally restricted homomorphism and constraint satisfaction problems. For every class of relational structures C, let LHOM(C, _) be the problem of d...

Local Search for Boolean Relations on the Basis of Unit Propagation
We propose a method for local search of Boolean relations relating variables of a CNF formula. The method is to branch on small subsets of the set of CNF variables and to analyze ...
