Battle of the Forgotten

Jabba better than expected.

Thanks a lot for the result, I'll post it on my blog

Richard

Hi Richard,

Not at all, Jabba is a nice engine.

Jabba was one of the first programs I was testing (before the "real" tournament began). I opted for keeping it in the tournament, in spite of the strenght showed until then.

Here is a logo for Jabba: (thanks to David Dahlem)



I am thinking about testing Lime, but I am afraid it would be too strong for this field. What do you think?

Regards,
Carlos

Thank you.

Interesting information about engines in 1800-2000 range of the ratings scale.

In fact it is even slightly below that:

The conditions to participate are:

1. Engines should have an approx. ELO of 1700 or lower.

which by no means makes it less interesting, of course.

[Richard Allbert]

Yes, I think Lime is too strong for the list!

Yes, I hadn't read that until later.

I did see the top 2 Jabba and KMTChess in there and thought these engines were around 2000 and ones below them were probably around 1800. Hence my assumption 1800-2000.

Ok Richard, thanks.

949 of 1560 games played

Buggy engines still in the tournament (I will take a decision about them later)

- Joana DC by Juan Pablo Mendoza (when playing with white pieces does not accept opponent's short castle and loses by time. 5 losses on time out of 38 games.)
- Yoda 1.30 does not accept opponent's underpromotion to other piece different of a queen. (as this happens ocasionally, Yoda won't appear in this list in the next update. Anyway, it seems Yoda is going to be removed at the end of the cycle being at the top10 right now.)

PS: I will travel in few hours, therefore I'll be far from my PC for some days. So, next update will be in 6 or 7 days.

[Carlos777]

I did see the top 2 Jabba and KMTChess in there and thought these engines were around 2000 and ones below them were probably around 1800. Hence my assumption 1800-2000.

Hi Swami,

Yes, I did not know too much about these engines at the time. As they had already played many games, I decided to keep them. Less strong engines will compete in the next cycle (this is the goal of this peculiar tournament ).

Best,
Carlos

Not working under Arena: (if someone has an idea on how to make them work, please reply)

ChessV 0.94

The engine command line for ChessV 0.94 has to be:

Code: Select all

ChessV_WinBoard "Orthodox Chess"

It seems that Arena cannot handle this (or people simply have not found out what they have to tell Arena to produce this command line when installing the engine).

Possible work-arounds are:

1) Put that command line in a batch file chessv.bat, and then install that batch file as an engine in Arena.

2) Make a ChessV .SGF file (saved-game file), say CHESS.SGF for the initial position of Orthodox Chess by saving from the stand-alone version of ChessV, or read the instructions that come with ChessV on how to make such a file for specifying variants, and follow those. Then install ChessV in Arena with the engine command:

Code: Select all

ChessV_WinBoard CHESS.SGF

so that you do not need the quotes around the argument that specifies the variant.

Even under WinBoard + PSWBTM I have to use the latter trick to make ChessV play Bird's Chess, as I have found no way yet to get the single quote in the variant name into the engine command line. With a bare WinBoard I can use /fcp={ChessV_WinBoard "Bird's Chess"}, but PSWBTM puts single quotes around the /fcp argument, and that is what makes WinBoard choke on it.

[metax]

What is the approximate rating scale for '1700 or lower'?

In CCRL rating, I would estimate ChessMind at 1930-1950 Elo based on games against Surprise. But in other rating scales, the ratings are often lower.

However, based on games against humans, I would estimate ChessMind at 1700-1750 'human Elo'.

I think in the CCRL rating scale Jabba would have around 1980-2000 Elo or even more.

[Adam Hair]

This is great Carlos. I've been working on a rating list since August
and I am including engines of all strengths. Here is the bottom of my
list. I plan to include as many engines as I can make run on my computer
under Arena 2.01.

Not working under Arena: (if someone has an idea on how to make them work, please reply)

ChessV 0.94

The engine command line for ChessV 0.94 has to be:

Code: Select all

ChessV_WinBoard "Orthodox Chess"

Hi HGM,

I tried adding "Orthodox Chess" in the command parameters box without success, I will try your suggestions when I back home.

Thanks,
Carlos
