Thanks, I certainly made something wrong, I will test again this week end, and try with Maia1.

Stockfish, Hiarcs and Deuterium v2019.2.37.73 are still close to FIDE Elo 1500.
On my computer (i5 2500k) when I run 100 games at 60s+100ms with Cheese 2.2 vs Deuterium 2.37.73, both at UCI_Elo = 1500, Deuterium is +188 ELO better than Cheese.

Am I doing something wrong ?

Re: UCI_Elo 1500 engines and FIDE Elo

You should try Cheese 2.2, I changed UCI_Elo calculation, based on a formula from one of your previous post. It's difficult to find a formula that works with all possible ELO values. In Cheese 2.2 there are 2 modes for UCI_Elo, in cheese.ini, UCILimitMode=0 to reduce the speed, or UCILimitMode=1 to ...

Re: Thought bitboards was faster :-)

Outside move generation Bitboards are also usefull (ex: mobility in evaluation function). Btw. intrinsics such as __builtin_ctzll(x) are not portable (this assumes a gcc or compatible compiler). C++20's <bit> header is one way to be more portable. Using compiler explorer (I don't have latest MSVC in...

Re: So what do we miss in the traditional evaluation?

Can we learn something from NNUE networks, using some kind of "reverse engineering" ? Maybe it's a bad idea but for example taking thousands of winning positions with passed pawns and looking at the highest values in hidden layers, then look at the inputs used to produce these values, is it possible...

Re: Laskas parameter optimizer

Right I see what you mean now. Thanks for your help. So if I let it end without interruption, it should print the best parameters ? (in my example the parameters from the first run ?) I forgot to say that I interrupt it manually because I don't know how much time I can let it running. This is my co...

When you resume you should see something like this: 2021-01-27 21:50:45,774 | INFO | oneplusone previous num_ask: 62 There is previous num_ask value. See your log_lakas.txt file. Yes I see a previous num_ask value when I restart, but every times I restart it uses the default init parameters as best...
