Seems to be the strongest x32 engine on one core.

Code: Select all

 2.  Strelka 5.5              	480.0/850	312-202-336  	(L: m=202 t=0 i=0 a=0)	(D: r=254 i=41 f=40 s=1 a=0)	(tpm=55.5 d=12.1 nps=968204)

  1 Strelka 5.5                    : 480.0/850  56.5   3223   18  18   39.5 %

Strelka 5.5 is stronger than Houdini 1.5a x32 on one core by 46 +/- 18 points (95%) at this ultra-short control, probably a bit stronger than Houdini 2.0.


I insert a dendrogram (the new Strelka included), closer to 0 on horizontal axis to the common "ancestor" - engines are more similar as move choices go.

IIRC it is not MP, is that still true?

I typed go depth 22 in Strelka 5.1 and Strelka 5.5 (both 32-bit versions) in console mode in an Intel i5-760 (2.8 GHz):

Exactly the same amount of searched nodes (345,308,824) for both versions! I do not know if this fact implies something or not... by the way, the speed of Strelka 5.5 was almost 3% faster than 5.1 version (in this sole sample).

The size of Strelka 5.5 is around 2.26 times bigger (in KB) than Strelka 5.1 size! If some experts (mainly programmers) can explain something (for example: if the fact of the same number of searched nodes at depth 22 means the same search algorithm in both versions), it will be highly appreciated. Thanks in advance and sorry for my dumbness regarding chess engines.

@Dr.Wael Deeb: thank you very much for posting the news of this release!

@Kai Laskos: thank you very much for these games! You were so fast. With a programme that I made in Fortran 95 I get an Elo interval of ~ ]+26.74, +63.95[ in favor of Strelka 5.5, for 2-sigma confidence (~ 95.45% confidence) using your data (+312 -202 = 336)... so it is more less what you get (I suppose you use BayesElo). Your dendograms are always useful, congratulations!

@Gerold Daniels: thank you very match for this test! I think that this TC will bring more accurate results than Kai's test (which is not bad).

@Albert Silver: AFAIK, regarding Strelka 5.x versions (5.0, 5.1 and 5.5), there are not MP compiles up to date. Anyway, I guess that any of Strelka 5.x engines will crush all of us, even on one core...

It's still a single processor version Albert
