Structural Symmetry Breaking

  title={Structural Symmetry Breaking},
  author={Meinolf Sellmann and Pascal Van Hentenryck},
Symmetry breaking has been shown to be an important method to speed up the search in constraint satisfaction problems that contain symmetry. When breaking symmetry by dominance detection, a computationally efficient symmetry breaking scheme can be achieved if we can solve the dominance detection problem in polynomial time. We study the complexity of dominance detection when value and variable symmetry appear simultaneously in constraint satisfaction problems (CSPs) with single-valued variables… CONTINUE READING
