Symmetry Breaking in Constraint Satisfaction with Graph-Isomorphism: Comma-Free Codes
In this paper the use of graph isomorphism is investigated within the framework of symmetry breaking in constraint satisfaction problems. A running example of Comma-free codes is ...

Compositional Derivation of Symmetries for Constraint Satisfaction
This paper reconsiders the problems of discovering symmetries in constraint satisfaction problems (CSPs). It proposes a compositional approach which derives symmetries of the appli...

Symmetries of Symmetry Breaking Constraints
Symmetry is an important feature of many constraint programs. We show that any symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different s...

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...
