Constraint Satisfaction with Bounded Treewidth Revisited
Abstract. The constraint satisfaction problem can be solved in polynomial time for instances where certain parameters (e.g., the treewidth of primal graphs) are bounded. However, t...

Equational Constraint Solving Via a Restricted Form of Universal Quantification
Abstract. In this paper, we present a syntactic method for solving firstorder equational constraints over term algebras. The presented method exploits a novel notion of quasi-solve...

Scheduling with Precedence Constraints of Low Fractional Dimension
Abstract. We consider the single machine scheduling problem to minimize the average weighted completion time under precedence constrains. Improving on the various 2-approximation a...

Learning Distance Metrics with Contextual Constraints for Image Retrieval
Relevant Component Analysis (RCA) has been proposed for learning distance metrics with contextual constraints for image retrieval. However, RCA has two important disadvantages. On...

Finding bugs with a constraint solver
A method for finding bugs in code is presented. For given small numbers j and k, the code of a procedure is translated into a relational formula whose models represent all executi...
