Great to have you here, Marco. The SugaR_xPrO and SugaR AI series of engines have been my favorites for a long time.

Look forward to testing your new creation.

Thanks Sarona ..
I certainly hope it is a versatile engine even if more can be done for the part that concerns the analysis
but it is a good compromise to please everyone .. (Machine room players and Iccf players)

They were my favorites until the appearance of Eman...

To be in a good hour, that's the comeback.

The arrival of an engine with his signature, is as always welcomed with applause in the community, because we know in advance, your high quality work in previous engines. At the moment I am working with StockfishMZ, I only have a doubt Mr. Zerbinati, the SugaR 2.50 experience file that I still use, is it possible to rename it and use it in this engine or will we definitely have to start from scratch? It may be a silly question, but it's an engine with your signature.

Thank you very much for your work.

Hi Anton,
the logic of the learning code is compatible
however, it makes little sense to use an experience file generated from another engine's ratings
Surely more correct to create a new one and train it with the usual patience.

Yes, it makes perfect sense, that's why I thought about it a lot before I asked. But it's okay with asking. Beauty of work! Regular training, perfect! Thank you so much for coming back with this great gift. Best wishes!

RIndex: Score according to solution time ranking for each position


The upper half of the list is much better as for rankings then the lower one as error bars show too, more than this too little numbers of solved positions with this hardware- time make the ranking less reliable per se.
I just give the whole list to show the numbers of listed engines because it's a measurement for the number of matches which are taken into account as for rankings and ratings.

EloStatTS doesn't count solved positions primarily, it compares each one time of solution of each position solved and unsolved of each one single engine to each one of all of the others, just like it does with results of engine- engine- games with EloStat from same author.

StockfishMZ- setting marked with ME-12-PE+12 has Materialistic Evalution Strategy set to minium, Positional Evaluation Strategy to maximum (+12), which makes a big difference here: -12+12-setting leading, default setting ranked as nr.10.
So it seems this one setting is tuned much better as for this one special test, at least as for this one NNUE (tried ShashChess and BlueMarlin already one more time too in meantime with nn-3c0aa92af1da.nnue, getting significantly less numbers of solved positions with both of them compared to the one but last green SF dev- net nn-d0b74ce1e5eb.nnue, they are still listed with above).

Thanks a lot for the new engine- branch replacing SugaR AI:

Well done finishing ahead of Crystal (and finishing first overall with modified settings) with this particular testsuite.  That is an excellent result posted from a highly respected tester, Peter Martan.

He occasionally posts at over at Talkchess, too. It was he that drew my interest in using EloStatTS (I use 1.04).

NO ! The default ones. SF-nn-3c0aa92af1da.nnue for StockfishMZ & SF-nn-6877cd24400e.nnue for EMAN 7.93. The same are the experience files. Interesting match.

Materialistic Evaluation Strategy, default 0, min -12, max 12
Positional Evaluation Strategy, default 0, min -12, max 12

ME-12 = Materialistic Evaluation Strategy -12 = min materialistic
PE+12 = Positional Evaluation Strategy 12 = max positional

So the engine doesn't care about the material on the board and searches for the best positional play = perfect settings for solving strategic test suites.
Of course with these settings, the scores of the StockfishMZ engine have nothing to do with the scores of the sfnnv5 net, and again less to do with the scores of Eman from the experience file.
It's very weird to use these "test suites" settings in a tourney where the goal is to predict the most opponent's moves in order to win the game, not to find the expected move of a test suite.

1) Materialistic Evaluation Strategy: Minimum = -12, Maximum = +12, Default = 0. Lower values will cause the engine assign less value to material differences between the sides. More values will cause the engine to assign more value to the material difference.
2) Positional Evaluation Strategy: Minimum = -12, Maximum = +12, Default = 0. Lower values will cause the engine assign less value to positional differences between the sides. More values will cause the engine to assign more value to the positional difference.

The default value for both options (0 = zero) is equivalent to the default evaluation strategy of Stockfish.
