I don't know much about R*, but I did consider doing A* in Python, and
gave it up because of the lousy performance of that kind of algorithm.
Are A* and R* relatives?
In general, my conclusion after doing numerical work for a while is that
the desire to look at algorithms crucial to your research as black boxes
is futile. In the end, I always had to dig into the details of the
algorithms because they were either never black-boxable or the black-box
versions didn't do a good enough job.
I wish you another conclusion, though. =)
