Hi,
I just want to share with you my experience with upgrading from Gecode
2.2.0 to 4.2.1.
I did most of the upgrade to version 4 in the Summer 2013. I had my own
implementation of Float Variables, a set of related propagators and
branchings, a related script/solver, a number of scheduling-related
custom propagators and several other mainly combinatorial int/bool
solvers using the standard Gecode stuff.
I must say that the transition was very smooth and the documentation
just rocks. I was able to abandon my Float Variables implementation and
use the built-in version instead. Also, as a benefit, the new version
seems to be more robust (I've seen rare crashes with the old version
that I attribute to the library.)
I look forward to exploring and using the new propagators (I've already
played with Hamiltonian path for example), and the new features like
restart-based search, symmetry breaking etc.
Thanks and keep up the good work!
Filip
