MinMax(void)
Default constructor.
int mi
Minimum of current range.
unsigned int width(void) const

Gecode toplevel namespace
Base for range iterators with explicit min and max.
int ma
Maximum of current range.
int min(void) const
Return smallest value of range.
bool operator()(void) const
Test whether iterator is still at a range or done.
int max(void) const
Return largest value of range.
