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...

Polyhedral representation conversion up to symmetries
We give a short survey on computational techniques which can be used to solve the representation conversion problem for polyhedra up to symmetries. In particular we discuss decompo...

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...

Machine Translation by Triangulation: Making Effective Use of Multi-Parallel Corpora
Current phrase-based SMT systems perform poorly when using small training sets. This is a consequence of unreliable translation estimates and low coverage over source and target p...

Discovering Near Symmetry in Graphs
Symmetry is a widespread phenomenon that can offer opportunities for powerful exploitation in areas as diverse as molecular chemistry, pure mathematics, circuit design, biology an...
