Hello,
Is it possible to translate in Oz in term of propagators this
"tuple-self-reference" constraint ?
Here it is :
%C is a tuple of M integers between 0 and N
{FD.tuple ProblemeDecoupage M 0#N C}
%All values are pairwise distinct in that tuple
{FD.distinct C}
%If a value is present in the tuple (for example C.1 = 1) then values 2,
3 and 7 are forbidden in the rest of the tuple
%I tried this but it doesn't worked :
Variable = (C.J =: I) %First
Contrainte = (C.J \=: {self getForbiddenValue(C.J)}) %Second
{FD.impl Variable Contrainte 1} % I wonder if this really "bind" the
second constraint to the first, as it is implied by the documentation's
"->" sign ... Therefore, the second constraint should be implied only if
the first is verified ?
By the way, are there (undocumented ?) propagators able to work with an
entire tuple at a time ? Being able to forbid a value IF another value
is present in the tuple would be great.
Any advise or help would be very appreciated !
Thanks !
Kim
