Subject: Hash table statistics

Author: Andrew Wagner

Hi all,

I'm using a simple hashing scheme: a single replace-always tranposition table.
I've made sure all the hash keys are correct by comparing it to a key created
from scratch. But I'm not sure it's working as efficiently as it could be. So,
my question is: what statistics can I generate that will tell me how it's doing?
And what values should I be getting for those statisics, on average?

Also, a slightly different topic: someone told me that with hash tables, and
without null-move, my move ordering (first-move fail-highs / total fail-highs)
should be averaging >95%. Does that sound right to the rest of you? Thanks!
Andrew
