ProB gets Nauty: Effective Symmetry Reduction for B and Z Models
Symmetry reduction holds great promise to counter the state explosion problem. However, currently it is “conducting a life on the fringe”, and is not widely applied, mainly du...

Calculating tree navigation with symmetric relational zipper
Navigating through tree structures is a core operation in tree processing programs. Most notably, XML processing programs intensively use XPath, the path specification language t...

Efficient local reflectional symmetries detection
In this paper, we present a novel framework for efficient multiple reflectional symmetric regions detection in real images. First, we present a fast operator to measure the symmetr...

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 ...

Orbital Branching
We introduce orbital branching, an effective branching method for integer programs containing a great deal of symmetry. The method is based on computing groups of variables that a...
