Detailed Description

template<class View>
class Gecode::Set::Int::ChannelBool< View >

Propagator for channelling between set variable and its characteristic function

Implements channelling constraints between BoolVar and a SetVar. For BoolVars $x_0,\dots,x_n$ and SetVar $y$ it propagates the constraint $x_i=1 \Leftrightarrow i\in y$.

Requires
