Symmetry breaking for set variables.

Function Documentation

template<class View >
 ValueSymmetryImp* Gecode::Set::LDSB::specialUpdate ( Space & home, ValueSymmetryImp< View > * s, IntSet usedValues ) ` [inline]`

Bulk update of a value symmetry s, using usedValues.

Calculates the intersection and difference of the values in the symmetry and usedValues, updates the symmetry to eliminate the used values, and makes a new symmetry containing the intersection values, if there are at least two. Returns the new symmetry, or NULL if the intersection has fewer than two elements.
