Hello George,

i think "arrow" is just the translation of the russian word "strelka"...

Yuriy's Strelka 5 has beat Vas to the punch. :) .

Code: Select all

    Program                            Score      %      Elo    +   -    Draws

  1 Houdini 1.5a w32               : 1242.5/2300  54.0   3214   11  11   35.9 %
  2 Strelka 5                      : 1057.5/2300  46.0   3186   11  11   35.9 %
It rocks, only 28 +/ -11 Elo points weaker than Houdini, clearly the second strongest program, and an untuned one! Now Yuri, tune it!

I have problems installing or running the engine on my W7-32 system.

In Fritz 10 and 12 it does not install.
In ChessPartner it does not run.
In Arena it does not run.

I simply extracted the beast with 7-zip, and then installed the .exe as a UCI engine. Did i miss some important step?

My best,
Kaj

You need to download this dll - put it in the strelka directory:

I am not so sure if 17-39 elo difference from houdini1.5 make it the second best engine..

The CCRL has the following for Critter and houdini at 40/40 and I do not know if strelka5 is better or worse than Critter.

Houdini 1.5a 32-bit 3205 +23 −22
Critter 1.2 32-bit 3158 +19 −19

Well, 100% sure one cannot ever be, but if you combine all the reasonable results (64 vs 64 or 32 vs 32, only few Elo points difference), for example this one too:

CCRL 40/4

Houdini 1.5a 64-bit 3266 +13 −13
Critter 1.2 64-bit 3209 +17 −17

then Critter 1.2 is ~50 +/- 10 (95% confidence) points weaker than Houdini 1.5a. Depends a bit on time control too.

It seems Yuri raped a bit Houdini 1.5. With Sim03 similarity tester I got the similarity matrix

Using IBM SPSS hierarchical clustering, the dendrogram is

Image

The distance on the horizontal axis to the common ancestor is the degree of relatedness. Strelka 5 seems _very_ related to Houdini 1.5, much more related than Houdini is to Ippos, or than Rybka 4 is to Rybka 3, for that matter.

Soon maybe I will post a dendrogram showing circumstantially that Fritz and Naum are Strelka/Rybka clones, therefore Fruit/Crafty clones as stated by ICGA.

What does untuned mean and why is everybody claiming Strelka 5 is untuned?
