Hier ist eine detaillierte Beschreibung des neuen Zeitmanagements, das als Grundlage die Verteilung/Absch├Ątzung der Bedenkzeit nach nodes/sec. vornimmt:

http://lczero.org/dev/docs/timemgr/

<@!450371839680708608> it tries to equalize total nodes per move, and not total time.
It's not the same as there is tree reuse. It also tries to account for earlier stop due to smart pruning.
Also the search is extended when max Q is not max N.

In diesem Test hat das neue Zeitmanagement schlechter abgeschnitten:

**Match:** Gauntlet 63700 vs SF11
**Hardware:** Geforce RTX 2070S & i7-5960X (8 cores/16 threads)
**Lc0 version (legacy):** v0.25.1
**Lc0 version (smooth):** 0.26.dev with PR1310
**Lc0 options:** Backend=cudnn-fp16 MovesLeftMaxEffect=0.2 MovesLeftThreshold=0.0 MovesLeftSlope=0.007 MovesLeftQuadraticFactor=0.85 MovesLeftScaledFactor=0.15 MovesLeftConstantFactor=0.0
**Additional Lc0 options (smooth):** --time-manager=smooth(init-piggybank=0.0,per-move-piggybank=0.18,max-piggybank-use=0.95,max-piggybank-moves=27.0)
**SF11 options:** Threads=14 Hash=1024
**Speed:** Lc0:11.4 kN/s, SF11:12554 kN/s (from benchmarks)
**Time control:** 15s+0.5s
**Book:** openings-8ply-10k.pgn, sequential, color reversed
**Tablebases:** 6-man syzygy
**Adjudication:** 6-man TB, -draw movenumber=50 movecount=5 score=8 -resign movecount=5 score=1000
**Software:** cutechess-cli

```diff

   # PLAYER                  :  RATING  ERROR  POINTS  PLAYED   (%)  CFS(%)    W     D    L

White advantage = 47.88 +/- 5.04
Draw rate (equal opponents) = 69.93 % +/- 1.24

```
Alles schwierig und theoretisch, aber so ist das bei Leela.
