Toga III 0.4 NNUE

[dkappe]

Based on d8 data from Toga II 4.0.2. My sense is that it’s a touch stronger than SF9.

I’ve finally had a little spare time to finish an initial port of NNUE to Toga II 4.01. It’s really more of a NN (missing UE) so somewhat slow. This is with the Toga 3 0.4 net. Need to train and tune the 0.5 net, get hybrid eval going, make it UE. Then will release it as Toga III on github.

I’ve checked in the initial nnue port here. https://github.com/dkappe/TogaIII/tree/nnue

[Pi4Chess]

Following with interest

[dkappe]

Slow as it is, I decided to try is against the latest Arasan.

Code: Select all

Score of arasan vs toga3: 44 - 23 - 33  [0.605] 100
Elo difference: 74.1 +/- 56.8, LOS: 99.5 %, DrawRatio: 33.0 %

Promising.

Also have night nurse running inside of a0lite julia for some shenanigans.
