Member Function Documentation

◆ varimp() [1/2]

template<class Var >
void Gecode::VarImpView< Var >::varimp ( VarImpType y)
inlineprotected

Set variable implementation to y.

Definition at line 453 of file view.hpp.

◆ afc()

template<class Var >
double Gecode::VarImpView< Var >::afc ( void  ) const
inline

Return accumulated failure count.

Definition at line 473 of file view.hpp.

◆ assigned()

template<class Var >
bool Gecode::VarImpView< Var >::assigned ( void  ) const
inline
