Hi,
I am inside a propagate method of a binary propagator... :)
At some point, I know that x0 is assigned. What I would like to do is
to filter the domain of x1 using a given predicate function.
if (x0.assigned()) {
IntVarValues r1(x1);
while (r1()) {
if (!my_predicate(x0.val(), r1.val()))
GECODE_ME_CHECK(x1.nq(home, r1.val()))
++r1;
}
return ES_SUBSUMED;
It does not seem to be a good idea however to alter the view x1 while
iterating over it...(is it true that this should not be done/will
cause problems?)
Hhm, could anyone give me a hint, what I could use in order to do
this safely?
Thanks a lot,
Kilian
