Well, you cannot rely on that no other propagator does it. At least not in real life...
What are you trying to do? If you have a propagator composed from a cheap and an expensive stage you might want to consider staged propagation. Just see the paper I mentioned before. We use it regularly in Gecode to great benefit.

Could you > elaborate, please? I was just wondering how the cost affected the ordering, but it seems that this is explained in the reference you just gave me. From a quick scan of it, it would seem that if i choose the highest cost (and no other propagators do the same), then i am in fact 100% sure that my propagator will only be asked to propagate when all other propagators have stabilized, which is exactly the effect i was hoping for. Thanks for the quick answer, you guys really have short response times :) Regards, Peter Tiedemann _______________________________________________ Gecode users mailing list [EMAIL PROTECTED] https://www.gecode.org/mailman/listinfo/gecode-users
