Subject: Debugging hash tables

Author: Andrew Wagner

Date: 04:30:24 03/13/04


Well, my program seems to have sufficient eval, but is always getting
out-searched (it only gets 4-6 ply in 15 0!). So I finally decided to implement
hash tables. I thoroughly tested all my hashing in my move-generation code, so I
am at least 99% certain that is correct. However, my evals are all over the
place. Some very strange scores, like +- 5 pawns in an even material position.
Anybody have some suggestions as to what hash statistics to produce and look at?
I don't know anything about hash table statistics. Thanks!
