New version chess engine: Lc0 BT4
LcZero - CEDR Rating=3683 vBT4: Big transformer 4. New network architecture which builds off of BT3 by adding two types of auxiliary heads, future heads and categorical value heads. The categorical value heads predict a distribution over values of q rather than a WDL outcome distribution, and the future heads predict the moves that will be played over the next two plies. The hope is that these heads will give additional information to the net to improve training speed. We've also fixed half-precision training, so this model will be larger. BT4 training started in mid-October and is expected to take a few months. It has 15 layers with 1024 embedding size, 32 heads per layer, and 1536 emb size, for roughly a doubling in size over BT3.

Why you lost your time whit weak engine ?? Komodo 14 is there for 2 mount and nothing ?? Why not compare Stockfish, Brainfish, Corchess6, Brainlearn, CFish, AsmfishW, Sugar Xpro, Fritz17, Sherdders13, Raubfish ,Houdini6, Fire and Ethereal in the same tournament. More than one tournament, whit different time control !!
ReplyDeleteWe test various engines, both powerful and weaker ones. We do not test commercial engines at all, because they are weaker than free ones and there are also controversies in relation to them (source codes).
