That's great to hear. I'm glad I'm not the only one interested in this
functionality.
Full support in the rules, instead, will take some more time. I would
like
to understand better what you mean by "uncertain planning": are you
considering actions with uncertain preconditions / effects or both? or are
you referring to randomized search algorithms?
Of course, you can always manage uncertainty explicitly, using additional
facts and calculating the probabilities, but I would not recommend that
unless you need a working prototype very quickly.
I'm mainly interested in planning with uncertain effects, similar to
what I've found in most probabilistic graphplan implementations (e.g.
http://www.cs.cmu.edu/~avrim/pgp.html).
Best,

p.s.
The paper you found is old and obsolete, definitely not worthy looking at (
shame on the main author ;) )
Heh, I'm glad you're still involved with the community after all these
years. Thanks for not dropping the research. I've seen a lot of
interesting graduate research just die as soon as the project/thesis
is over.
