[gecode-users] Dynamic Branching Support?

[Matthias Goldhoorn]

Hi to everyone on the ML,
i'm new to gecode and have already a kind of bug problem .

My Search will not Terminate within days. I have several SetVarArrays, 
BoolArrays and so on on my Space.
The Solutions they are found are valid for me, but the search is simply 
to slow (and sometimes to memory exhaustive).
I used already gist for introspection, my problem is that i first branch 
on a BoolVarArrays which reduces the search space quite well until a 
spefici point. At this point i would like to keep Post prune the 
BoolVarArray and Continue branching on a SetVarArray. This wold faster 
reduce my search space than continue the branching on the Bool one.

My question therefore is: is there a way to select dynamically the 
branching set?. I found on the documentation that it is possible to 
select a variable INSIDE a structure for branching. But that i need is a 
dynamic selection of the Set/Array where the branching should be done. 
Is this possible in gecode. Or (@dev's) is the extension possible?

Best,
Matthias

(P.S. Since i do open-source development i could provide my application 
if this helps the understanding.)
