Well, I have no real idea. One thing of course is that one branching is
worse, so you need more search and that takes more nodes and hence memory.
Then, the other thing is: does your branching have a big state? Or does it
reference lots of variables (remember: variables are kept alive by
propagator and branching, if a variable is not reference it will just go
away).
That's all what I would know

Subject: [gecode-users] Tracking memory usage
I am applying two different (custom) branchings to the same constraint
problem and one of them is reporting a lot more memory use (via
Statistics) than the other. This is not completely unexpected but the
difference is big enough that it requires more careful analysis to
make sure it isn't just the result of an implementation flaw.
Is there any way you can recommend to track memory usage in a more
fine-grained fashion?
Malcolm
