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...

Efficient Symmetry Breaking for Boolean Satisfiability
Identifying and breaking the symmetries of CNF formulae has been shown to lead to significant reductions in search times. In this paper we describe a more systematic and efficient...

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...

An Attempt to Dynamically Break Symmetries in the Social Golfers Problem
A number of different satisfaction and optimisation combinatorial problems have recently been approached with constraint programming over the domain of finite sets, for increased d...

Bit complexity of breaking and achieving symmetry in chains and rings
We consider a failure-free, asynchronous message passing network with n links, where the processors are arranged on a ring or a chain. The processors are identically programmed bu...
