You first have to check with any()! Only if that is false, min and max make
sense!

Hi everybody,

in case of the modification event Gecode::Int::ME_INT_VAL i want to know
what is the meaning of the IntView::min(d) and max(d) methods (d==delta)

In the case of ME_INT_BND,
min(d)..max(d) is the range that was removed from the domain.

In the case of ME_INT_VAL
i sometimes have it being a removed range, but sometimes it is min(d)=1 and
max(d)=0.
I thought that this means that the domain was restricted on both sides of
the variable, eg. x==6 while it was x = [1..10] before.
But this does not seem to be true in all cases.
So what is the meaning of these values.

Best,
Max
