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...

Model Restarts for Structural Symmetry Breaking
ctural abstractions that were introduced in [17]. Compared with other symmetry-breaking techniques, the big advantage of dynamic symmetry breaking is that it can accommodate dynami...

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...

Dynamic Lex Constraints
Many symmetry breaking methods have been proposed so far. Previous works have shown that these methods could be combined together under some conditions. We use a different angle :...

New Developments in Symmetry Breaking in Search Using Computational Group Theory
Symmetry-breaking in constraint satisfaction problems (CSPs) is a well-established area of AI research which has recently developed strong interactions with symbolic computation, i...
