void Gecode::notMax ( Space &  home,
SetVar  s,
IntVar  x 
)

Post propagator that propagates that x is not the maximal element of s.

Definition at line 144 of file int.cpp.

void Gecode::max ( Space &  home,
SetVar  s,
IntVar  x,
BoolVar  b 
)

Post reified propagator for b iff x is the maximal element of s.

Definition at line 149 of file int.cpp.

void Gecode::channel ( Space &  home,
const IntVarArgs &  x,
SetVar  s 
)

Post propagator for $\{x_0,\dots,x_{n-1}\}=y$ and $x_i<x_{i+1}$.

Post propagator for $x_i=1 \Leftrightarrow i\in y$.

Definition at line 156 of file int.cpp.

void Gecode::channel ( Space &  home,
const IntVarArgs &  x,
const SetVarArgs &  y 
)

Post propagator for $x_i=j \Leftrightarrow i\in y_j$.

Definition at line 163 of file int.cpp.

void Gecode::cardinality ( Space &  home,
SetVar  s,
IntVar  x 
)

Post propagator for $ |s|=x $.

Definition at line 58 of file cardinality.cpp.

void Gecode::weights ( Space &  home,
const IntArgs &  elements,
const IntArgs &  weights,
SetVar  x,
IntVar  y 
)

Post propagator for $y = \mathrm{weight}(x)$.

The weights are given as pairs of elements and their weight: $\mathrm{weight}(\mathrm{elements}_i) = \mathrm{weights}_i$

The upper bound of x is constrained to contain only elements from elements. The weight of a set is the sum of the weights of its elements.
