Detailed Description

Note:
Domain consistency on the extended cardinality variables of the Global Cardinality Propagator is only obtained if they are bounds consistent, otherwise the problem of enforcing domain consistency on the cardinality variables is NP-complete as proved by Qumiper et. al. in ''Improved Algorithms for the Global Cardinality Constraint''.

Function Documentation

void Gecode::count ( Home  home,
const IntVarArgs &  x,
int  n,
IntRelType  r,
int  m,
IntConLevel  icl = ICL_DEF 
)

Post propagator for $\#\{i\in\{0,\ldots,|x|-1\}\;|\;x_i=n\}\sim_r m$.

Performs domain propagation but is not domain consistent.

void Gecode::count ( Home  home,
const IntVarArgs &  x,
const IntSet &  y,
IntRelType  r,
int  m,
IntConLevel  icl = ICL_DEF 
)

Post propagator for $\#\{i\in\{0,\ldots,|x|-1\}\;|\;x_i\in y\}\sim_r m$.

Performs domain propagation but is not domain consistent.

void Gecode::count ( Home  home,
const IntVarArgs &  x,

)

Post propagator for $\#\{i\in\{0,\ldots,|x|-1\}\;|\;x_i=y\}\sim_r m$.

Performs domain propagation (icl = ICL_DOM, default) and slightly less domain propagation (all other values for icl), where y is not pruned. Note that in both cases propagation is not comain consistent.

Performs domain propagation but is not domain consistent.

Throws an exception of type Int::ArgumentSizeMismatch, if x and y are of different size.
