Classes of Submodular Constraints Expressible by Graph Cuts
Submodular constraints play an important role both in theory and practice of valued constraint satisfaction problems (VCSPs). It has previously been shown, using results from the ...

Experimenting with Small Changes in Conflict-Driven Clause Learning Algorithms
Experimentation of new algorithms is the usual companion section of papers dealing with SAT. However, the behavior of those algorithms is so unpredictable that even strong experime...

A Geometric Constraint over k-Dimensional Objects and Shapes Subject to Business Rules
This paper presents a global constraint that enforces rules written in a language based on arithmetic and first-order logic to hold among a set of objects. In a first step, the rul...

Connecting ABT with Arc Consistency
ABT is the reference algorithm for asynchronous distributed constraint satisfaction. When searching, ABT produces nogoods as justifications of deleted values. When one of such nogo...

Approximate Compilation of Constraints into Multivalued Decision Diagrams
We present an incremental refinement algorithm for approximate compilation of constraint satisfaction models into multivalued decision diagrams (MDDs). The algorithm uses a vertex ...
