Symmetry Breaking as a Prelude to Implied Constraints: A Constraint Modelling Pattern
Finite-domain constraint programming can be used to solve a wide range of problems by first modelling the problem as a set of constraints that characterise the problem’s solutio...

Solving Necklace Constraint Problems
Abstract. Some constraint problems have a combinatorial structure where the constraints allow the sequence of variables to be rotated (necklaces), if not also the domain values to ...

Breaking Symmetry of Interchangeable Variables and Values
Abstract. A common type of symmetry is when both variables and values partition into interchangeable sets. Polynomial methods have been introduced to eliminate all symmetric soluti...

Symmetry Breaking for Maximum Satisfiability
Symmetries are intrinsic to many combinatorial problems including Boolean Satisfiability (SAT) and Constraint Programming (CP). In SAT, the identification of symmetry breaking pred...
