[gecode-users] reified domain constraints failing for empty domains

[Kish Shen]

Hi,

I have noticed that the reified version of the dom constraint seems to 
fail when the domain is empty (min > max):

dom(*solver, x, min, max, reif)

solver->failed() seems to return true if min > max, even if reif is not 
set, or 0.

To me, it seems more correct for dom to succeed if reif is 0, and to not 
fail if reif is not yet set to 0 or 1. Is it possible to do this?

Thanks and cheers,

Kish
