Subject: Hash probe success rate

Author: Andrew Wagner

Date: 11:19:02 06/30/04

I have a single transposition table, replace-always. I count a success when I
get back a score which allows me to return immediately, without making a move.
About what percent should my success rate be?

Currently, my success rate starts around 5%, then drops turn-by-turn, until it's
0, then jumps back up and starts falling again. Any suggestions what might be
causing this? I've tested all my keys with generating them from scratch, and
have no problems there. My code is modelled after the TT code on bruce morelan's
site. Any suggestions appreciated....
