Automatic Detection of Variable and Value Symmetries
Abstract. Many symmetry breaking techniques assume that the symmetries of a CSP are given as input in addition to the CSP itself. We present a method that can be used to detect all...

Breaking All Value Symmetries in Surjection Problems
We propose a surprisingly simple new way of breaking all value symmetries with constraints. Our method requires the addition of one variable per value of the problem plus a linear ...

Tree Decomposition with Function Filtering
Besides search, complete inference methods can also be used to solve soft constraint problems. Their main drawback is the high spatial complexity. To improve its practical usage, w...

On Solving Soft Temporal Constraints Using SAT Techniques
In this paper, we present an algorithm for finding utilitarian optimal solutions to Simple and Disjunctive Temporal Problems with Preferences (STPPs and DTPPs) based on Benders’...

Towards an Optimal CNF Encoding of Boolean Cardinality Constraints
We consider the problem of encoding Boolean cardinality constraints in conjunctive normal form (CNF). Boolean cardinality constraints are formulae expressing that at most (resp. at...
