Hi Guido,

Thanks for your reply.

It won't be part of the unary constraint, because it's really not tied to any particular resource, but it's shared between all resources (tasks can be on more than one resource, but there's only one order among all tasks).

Is this information tied into gecode's search engines? That is, would 
the booleans be available for explicit labelling by the programmer? I 
ask this because the ECLiPSe gecode interface allows the search to be 
done from ECLiPSe.

Cheers,

Kish
