Hi Filip,

Great to hear that the ride was smooth and the documentation helps.

Thanks for the kind words

Cheers

Subject: [gecode-users] Upgrading from Gecode 2.2.0 to 4.2.1

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
