Krzysztof, thanks for answering.
The background of my question is related to the loss of Dragon.
According to my analysis, them main error from dragon was move 51. ... 33-29, which yields a loss, whereas 7-11 is a draw,
I hope Ed can also analyze the position/game.

I don't expect a program like ...

Krzysztof,

which programs played in the 3th round on the computer with the memory fault?
As this could impact results, although i assume probability is maybe low.

Bert

Gijsbert, are these games from a DXP-match (158 games)?
What were the settings, such as game time and number of cores used?
And what was the final outcome in match result?

Think Kingsrow is (still) the best match player, maybe only Ares has a comparable match-result (or maybe slightly better).

In ...

There are rumors that the ZEN 6 will have a boost clock above 6 GHz, so also this record will not be for eternity.

Ed, you are right with bulk-counting the result for the initial positions is 32.8 seconds.

The perft result from Ed was (most likely) without bulk-counting, which should not be neglected.

Joost, nice result!
When Ed published his first perft result (initial position) in 2008, the time was 55.86 seconds.

Frank, absolutely.
Think that is one of the reasons (I guess) for (as an example) the strength of Kingsrow.
Tested in detail, and if I'm correct every new idea was tested with at least 10K games against the previous program.
Therefore I also don't understand the weird graph of the Dragon game.
Maybe ...

It is not a surprise that the 4th example again involves Truus. Here the game Tornado - Truus. The outcome would have been a draw, if Truus did not make a final mistake on the 48th move by playing 20-24? whereas 10-15 would have resulted in a draw.
See graph.

For an unknown reason Truus is always involved in the first 3 example. Here in the game GWD - Truus. The graph shows that GWD got a winning advantage but made an error, and the score suddenly dropped. As Truus also made a mistake later, the game ended after almost 100 moves in a win for GWD. Unknown ...

As I shared before, with so many programs now in the top league, one sometimes need to have a little luck to win against the weaker opponents. Having said that, although this statement might be true, I guess that the top 3 programs really deserve the medals!
A good example, of a "little help from my ...

Thanks for posting the pdn file. I tried to do a bulk-analysis of all games. Unfortunately my program stopped at game 127.
Anyway, found some interesting games. Sometimes the end-result does not reflect what happened beneath the surface.
A good example is the game Dragon - Truus. here both programs ...

Sidiki, guess for bulk analysis one file would really help me.

Bert

Sidiki, could you post a pdn-file with all the games. Or is this already included on the website?

Bert

Sidiki, first of all thanks for organizing this interesting tournament.

Also congratulations for the winner Ares en runner-up GWD.
In the end the win from Ares against Dragon was decisive for the end result.
This was the only non draw game between the top programs.

This tournament once again ...
