I would start with the two stage approach, there is nothing wrong with that as far as I can see.

Subject: [gecode-users] 2-stage optimisation
I would like to realize a 2-stage optimisation. More precisely, a first phase using a branch-and-bound algorithm provides me with an upper bound that is used to constrain the second phase.
My question is the following: do I have to declare two spaces and two engines to achieve this or is there a better way of doing ?
Thanks in advance.
