Subject: Tablebases : Formula for calculalting file size?

Author: Roy Brunjes

My apologies for asking this if it was previously discussed ...

As computers head toward the 100 TB disk storage range, and not too far away are
systems with 1 PB (Peta Byte) of storage online (1,000 TB = 1 PB), how long
before we will see really large tablebases being built?  [8, 9, 10 pieces]

And what is the formula used to compute the size required to store all n piece
tablebases?  Of course, if it were possible (and I doubt it is for the
forseeable future), how large would a 32 piece tablebase set be?  At that point,
chess is no longer a mystery for the machine of course.

Anyone know the formula [obviously an exponential, but what is the formula]?  I
suspect Bob Hyatt knows -- Bob are you reading this?

Thanks,

Roy
