Hello Krzysztof Grzelak

Could a final stage be added to the tournament?
My suggestion is: after the tournament all against all ends, the top four who face each other in a semi-final, the first against the fourth and the second against the third, whoever wins goes to the final. It would be very interesting to see a match between the best placed in the tournament.

Krzysztof

Hi Krzysztof, thank you for organizing this event.

I will try to follow it online whenever I can.

Good luck!

Joost

[Joost Buijs]

Hi Krzysztof,

What does the column "No O.(W)" in the cross-table represents? And what happened to "SB" (Sonneborn Berger)?

Joost

[Krzysztof Grzelak]

The criteria for the tournament are as follows and the regulations say about it:

- total score - Total
- better result with the best opponents - No O.(W)
- number of wins - Wins

There is no factor S.B.

Krzysztof

[Joost Buijs]

Hi Krzysztof,

I assumed you would use SB as "better results with best opponents".

Can you tell how "No O.(W)" is calculated, I mean the formula?

Joost

[Krzysztof Grzelak]

Hi Krzysztof,

I assumed you would use SB as "better results with best opponents".

Can you tell how "No O.(W)" is calculated, I mean the formula?

Joost

I will answer this question later. I will just write that there was a discussion on the forum not to use the factor S.B. Link to the discussion of the factor per tournament viewtopic.php?f=53&t=8465

Of course, this has been programmed by somebody else. Personally I think SB would be good enough. I understand that you really insist on using the number of wins as a tiebreaker, in this case it would be fair to look at the number of losses too. Just my 2 cents.

@Joost.

It is: the best result obtained in order of the classification, e.g. the preceding tie-break criteria.

Consider the following example:

Arbiter Pro offers a selection of tie-breakers. According to the official website the following choices has been made:

the place of the program in the tournament is determined by the following criteria tie break:
- total score, better result with the best opponents, number of wins.

If two players tie based on best result, then number of wins and SB will also make no difference.

Thanks for the example! Now I understand what it actually does.

Against this criterion you could argue (as Ton Sijbrands did, if I'm not mistaken) that the top players will play even more carefully, because a defeat against a direct competitor is fatal. But in a tournament between computer engines this seems to me to be an advantage. A win against a direct competitor is rewarded extra. I see this as an improvement over the SB tie-break.

It is also a strong decision maker because a tie in a double round-robin tournament is very unlikely.

[Jelle Wiersma]

Considering
- every programmer can change versions of its software twice during tournament
I supplied Krzysztof with a bugfix for isolated man (geisoleerde schijven); in Round 9, in the game Moby Dam vs. Sjende Blyn, the man on 22 was wrongly considered to be isolated.
