Subject: Retire "Active reparenting"
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=be3b8f3ae939b19dfd36ebff3f485395083a3ab9;hp=be3b8f3ae939b19dfd36ebff3f485395083a3ab9;ds=sidebyside

Retire "Active reparenting"

After 6K games at 60" + 0.1 on QUAD with 4 threads
this implementation fails to show a measurable increase,
result is well within error bar.

Perhaps with 8 or more threads resut is better but we
don't have the hardware to test. So retire for now and
in case re-add in the future if it proves good on big
machines.

The only good news is that we don't have a regression and
implementation is stable and bug-free, so could be reused
somewhere in the future.

No functional change.
