Hmmm, something is still strange.
K2 (0.95/0.96) was a main sparring partner of OliThink.
They played more millions games and OliThink 5.9.1 beats K2 quite easily with an ELO diff of about 130.

Code: Select all

delocto         uci     -5      0.6     https://github.com/moterink/Delocto
drosophila      uci     -260    1.6     https://github.com/gustafullberg/drosophila
k2              xb+uci  -130    0.96    https://github.com/serg-meus/k2
olithink5       xboard  0       5.9.1   https://github.com/olithink/OliThink

Of course I never do 25 minutes for 40 moves, because I need quickly many games.
But changing time controls never affected the results against K2.

This is a general observation that other engines do much better in those tournaments compared to my results.
What could this be?

PS: With Drosophia it's an ELO diff of about 260 and yet Drosophila has 15 points and OliThink 17...
PPS: Delocto???

Small sample size, plus the unpredictability that tournaments can throw up.
OliThink 5.9.2 64-bit is performing around 2750 Elo in CCRL after a small number of games, but the gauntlet I'm starting today will sort out how accurate that rating is.

Thank you so much, Graham! You are such a huge support for the chess programmer community!

You are right about the small sample size, but there is a pattern that I observe since quite some time in other tourneys, too.

Actually I am running a Gauntlet, too, on my 32-core Linux server with 32 concurrent games. It's the same time control as yours, 25 minutes for 40 games and ponder off.
Differences: I am using 3moves book with thousands of opening, no tablebases at all, machines use their default hash size.

So there are not that many games, the error is still quite large. It's running for 12 hours and this is an intermediate result :

Code: Select all

   # PLAYER            :  RATING  ERROR  POINTS  PLAYED   (%)    W    D    L  D(%)  CFS(%)
   1 OliThink 5.9.2    :       0   ----   145.0     198  73.2  119   52   27  26.3     100
   2 Delocto 0.6       :    -121     75    22.5      66  34.1   12   21   33  31.8      93
   3 K2 v.0.96dev      :    -202     77    16.5      66  25.0    8   17   41  25.8      75
   4 Drosophila 1.6    :    -241     86    14.0      66  21.2    7   14   45  21.2     ---

White advantage = 80.18 +/- 24.87
Draw rate (equal opponents) = 33.23 % +/- 4.29

Of course we have to consider the fact that OliThink has been developed on that very Linux server, so it's optimizied for that.
Other than that, there is notable difference in terms of performance which I cannot explain.

[JohnWoe]

Thank you for testing Mayhem!

Nice to see Mayhem playing good games. Especially nice wins against Olithink
These results are pretty much what I got testing Mayhem 2.5 vs Glaurung 2.2. The games were really hard fought and score ~50%.

Anyway Mayhem 2.7 is going to be much stronger. It has the most important EGTB 4 - 7 men internally. Null move bug is fixed...
