Subject: MTD(f) and storing the PV

Author: Tord Romstad

I am currently experimenting with MTD(f).  There are still a few bugs left
to fix, but it mostly seems to be working OK now.  However, there is one thing
I haven't been able to figure out:

Is there an easy way to store the PV in MTD(f)?  Currently I just construct a PV
from the hash table after each iteration.  This works, but is somewhat messy and
inconvenient.  Is there a better way to do it?
