Detailed Description

An element constraint selects zero, one or more elements out of a sequence. We write $ \langle x_0,\dots, x_{n-1} \rangle $ for the sequence, and $ [y] $ for the index variable.

Set element constraints are closely related to the element constraint on integer variables.

void Gecode::element ( Home  home,
SetOpType  op,
const SetVarArgs &  x,
SetVar  y,
SetVar  z,
const IntSet &  u = IntSet(Set::Limits::min, Set::Limits::max) 
)

Post propagator for $ z=\diamond_{\mathit{op}}\langle x_0,\dots,x_{n-1}\rangle[y] $.

If y is the empty set, the usual conventions for set operations apply: an empty union is empty, while an empty intersection is the universe, which can be given as the optional parameter u.

The indices for y start at 0.
