Go up one level in this thread
Realized after I sent last message that these might help you out a little too:
Hash probes: 357103 Hash stores: 159816
hit exact: 2084 store exact: 1166
hit upper: 13164 store upper: 52337
hit lower: 164747 store lower: 106313
hit unusable: 101410 store nulllw: 0
deep/fast: 257292 / 68267 (72.05% / 19.12%)
Efficiency: 91.17%
Probes is calls to HashLookup. Hit exact is exact hits with enough draft to
use. Hit upper/lower is enough draft and usable with current A/B to cause a
cutoff. Unusable is not enough draft (but still ordered first).
Stores are exactly what you think. Store nulllw is lower bounds stored after a
null move cutoff. The deep/fast numbers are for the two halves of the
transposition table... one implements deeper-only replace and the other always
replaces. These tables are the same size currently although I would be
interested in anyone with experience shrinking the always replace table... The
efficiency numbers include unusable hits (basically if I match a sig in the hash
the numerator of the efficiency ratio increases. The denominator is the total
probes). These numbers are from the output of that same 5 sec search I am
following up to.
Good luck!
