3. Neues Optimum bei den Parametern:

**Match:** 780977 optimum 1 vs 780977 optimum 2
**LC0 version:** v0.28
**LC0 options:** --smart-pruning-factor=1 --minibatch-size=64 --cpuct-factor=3.973 --cpuct-base=45669
**Hardware:** EPYC 74F3 + A100
**Time control:** 10k npm
**Book:** book-ply8-unifen-Q-0.25-0.40.pgn
**Tablebases:** no
**Adjudication:** -resign movecount=2 score=500 twosided=true -draw movenumber=50 movecount=20 score=10
**Software:** cutechess-cli
**Comment:**
Optimum1: --cpuct=1.25 --fpu-value=0.15 --policy-softmax-temp=1.0
Optimum2: --cpuct=1.97 --fpu-value=0.55 --policy-softmax-temp=1.5

```
