Does this mean that creating a VarMap is not only achieved by putting
the VarArray but also by iterating all the actors?.
I mean, for the queens problem for instance, the following two codes
do the same in which respects to filling a VarMap?
code 1:
VarMap * exportVars(void) {
VarMap *vmp = new VarMap();
Support::Symbol symb("root",true);
vmp->putArray(this,q,symb);
return vmp;
}
code 2:
VarMap * exportVars2(void) {
VarMap *vmp = new VarMap();
SpecIter si = actorSpecs(*vmp);
while (si())
++si;
return vmp;
}
If that is true i find the second a more general approach, since it
automatically collects only variables related to constraints.
