Hi
Are the values sorted? They must be even though the documentation doesn't
say it (damn).

Subject: [gecode-users] Value intersection problem
Hi
I am trying to restrict the values of an IntView by doing the following:
...(values is given as parameter for the method containing this code, the
type is const set<string>& )
vector<string> v;
for(set<string>::const_iterator setIt = values.begin(); setIt!=
values.end(); setIt++)
{
v.push_back(*setIt);
}
GECODE_AUTOARRAY(int,restrictedDoms,v.size());
for(int i=0;i<v.size();i++)
{
restrictedDoms[i] = atoi(v[i].c_str());
}
Gecode::Iter::Values::Array restrictIterator(restrictedDoms, v.size());
return iv.inter_v(homeFZ, restrictIterator, false);
---
I can inspect the code and see that the values contained in "restrictedDoms"
are the values 1 to 10. Furthermore I can see that iv.size() is 10 (values 1
to 10) before the call to inter_v (and unassigned of course). Then after the
call to inter_v, iv is assigned, and I can see that the value it is assigned
to is the first value in the restrictedDoms array.
So what am I doing wrong?
Thanks!
Andreas
p.s. Of course it is useless to intersect a variable with domain 1 to 10
with the values 1 to 10, but still the behavior is unexpected.
