STSM by Karpas Erez to the University of Freiburg

I am happy to report that my STSM to the University of Freiburg was a success.
We were able to build a foundation for much easier continued development of the Fast Downward planning system,
by switching to a distributed source control system, which would allow much easier parallel development, and by
automating the building and testing process using buildbot.
We were also able to work on making the planning system much more flexible than before, by introducing problem transformations,
which are a very general way of doing many interesting things.
Finally, we were able to decide upon our various entries to IPC-2011, the international planning competition,
and hope to
see good results there.
In addition, my discussions with people there have led to several interesting new research ideas.
