It's the same. When activated in the script it does it automatically for you (acquiring wakelock before and releasing wakelock after tournament).
I will try the new version since it can automatically activate/deactivate.

Re: Training positions

Before I proceed into implementing my own NNUE architecture and version I would like to improve my hand crafted eval first as I will use it later to train my own NNUE net. I think the strength of Invictus is enough to generate a good training positions for NN. Depth 5 test: Rank Name Elo +/- Games ...

Re: Juste pour éclairer ma lanterne

Bonjour la Communauté. Juste une petite question pour éclairer ma petite lanterne. J'ai parcouru le script Python (qui fonctionne très bien) et essayé de comprendre les calculs effectués pour le Rating ELO et autres. Or, deux variables (ou constantes) ont une valeur dont je ne sais d'où elles provi...

Re: NNUE scoring (egbb lib)

As said if you are going to use NNUE in a simple engine (TSCP type) that only uses the evaluation on the leaves of the tree, then it is not necessary to do any tuning or scaling of the evaluation. If the engine uses the evaluation on each node of the search for pruning (razoring, null move, static ...

Re: NNUE scoring (egbb lib)

To be honest, i do not understand the scaling with the 50 move counter, at least not in first go. I think i got the idea to stop moving pieces over the board forever, but how does it help if you scale down any output of the net. Don't you produce just smaller score and the decisions in the tree kee...

Re: NNUE scoring (egbb lib)

Hello everybody. I did already read the thread but i still need to ask again. 1. What range of scores will the NNUE provide. I want to be sure, there are no scores outside my mate bounds ? Depends on how the nnue is generated. Another way to check is by testing it with mate in 1 and mated in 1 posi...

Re: Search tuned depending on TC

Good point even HCE is affected by time. Your idea of applying time in pruning/reduction is interesting. With more time one may scale down the eval i.e relying more on the search.
