Rebel 16.2 beta Empty
PostSubject: Rebel 16.2 beta   Rebel 16.2 beta EmptyTue Feb 14, 2023 1:22 pm

Got this from Thorsten who is testing the beta version. No considerable elo changes or it must be the time control and/or permanent brain. First test, I understand more is coming.

Code:

Rebel 16.2 beta Empty
PostSubject: Re: Rebel 16.2 beta   Rebel 16.2 beta EmptyWed Feb 15, 2023 3:37 am

Very soon all the Neural Net chess engines will have the same Elo rating. In my test the top 3 chess engines have a Elo difference of 7 Elo.  lol!

Hardware does not matter much. Over threading the NN with too many threads. Does seem to have a negative impact on performance. Most likely caused by the programmers not testing the engines with huge thread loading. And correcting the issues.

Code:
