Berserk 9 released.

Writer's picture: DariusDarius

One of the most powerful chess engines has been released in version 9.


Here's what Jay Honnold wrote about Berserk 9:


"

Another release for Berserk! This patch sees major changes in NNUE and many minor adjustments in search.


This patch introduces a new architecture in Berserk, a horizontally mirrored 8 bucket system. This results in a 6144 -> (512x2) -> 1 final architecture. This network was trained using Koivisto's Trainer using ~8B FENs from Berserk 8.5.1 self play games.


Along the way of working on NNUE, many minor search patches have been added. They were all minor, but lots of small changes add up.
