Detailed Description

template<class Card>
class Gecode::Int::GCC::Dom< Card >

Domain consistent global cardinality propagator.

The algorithm is taken from: Claude-Guy Quimper, Peter van Beek, Alejandro López-Ortiz, and Alexander Golynski. Improved Algorithms for the Global Cardinality Constraint, CP 2004, pages 542-556.

Member Data Documentation

template<class Card>
ViewArray<IntView> Gecode::Int::GCC::Dom< Card >::x [protected]

Views on which to perform domain-propagation.

Definition at line 222 of file gcc.hh.

template<class Card>
ViewArray<IntView> Gecode::Int::GCC::Dom< Card >::y [protected]

Views used to channel information between x and k ($ x \subseteq y $).

Definition at line 227 of file gcc.hh.

template<class Card>
ViewArray<Card> Gecode::Int::GCC::Dom< Card >::k [protected]

Array containing either fixed cardinalities or CardViews.

Definition at line 229 of file gcc.hh.

template<class Card>
VarValGraph<Card>* Gecode::Int::GCC::Dom< Card >::vvg [protected]

Propagation is performed on a variable-value graph (used as cache).

Definition at line 231 of file gcc.hh.

template<class Card>
bool Gecode::Int::GCC::Dom< Card >::card_fixed [protected]

Stores whether cardinalities are all assigned.

If all cardinalities are assigned the propagation algorithm only has to perform propagation for the upper bounds.
