IPON will change ...

Post by IWB »

... and as a preparation for that I played a tourney with the top 19 engines (Top 20 - F13) with a set of new 25 openings.

That is a new set of 8550 games.

The result of that individual tourney might interest a few:

So the IPON will grow, the 'secret' is that it will be played with 75 opening and not with 50 (old 50 + 25 new), therefore "just" with the top 20 engines.

Exact rating and details later this weekend, but I can already say that nothing serious changes. Basicaly all enignes came out well within their error ranges of the "old" IPON. It might be that one or th eother engine will change ranking if they are very (!) close together but rating will come out very similar ...

hello....
Earth to Ingo!

your IPONtificate rating list appears to be a complete farce...

it doesn't matter that you're finally attempting to 'correct' your opening book issues...
without Ivanhoe playing, the claim that you're testing the 'top 19 engines'? is nothing more than a perverted fantasy.
:lol:

PS-
you are promoting and testing clearly GPL plagiarized engines like Houdini, Rybka, Strelka, etc.,
while simultaneously blacklisting a clean, unique, and incredibly innovative engine like IvanHoe?

:shock:
can you hear me Major Tom?
are you sitting in a tin can?

Come on, don't you see that the general consensus is to use whatever open sources out there, if possible, without mentioning them, then to try to make the same open sources look silly? I think this trait is a particular example of how one succeeds in the modern, noble life.

Fire, Ivanhoe, RobboLito are not in the list ?

Why then are Strelka, Houdini, Rybka, Protector, etc. in it ?
My engine was quite strong till I added knowledge to it.

Protector is not a controversial engine as far as I'm aware.

The question is comming up from time to time and is basicaly answered with my rules but here in more details (Maybe I put this onto my page, but noone is reading condition/rules or remarks anyway)

I did test a few of the mentioned for my private entertainment but do not publish because of:

Ivan and Robo are anonymus authors and I only accept engines with a known author. It is a matter of fairness for the honest authors. Fire with its history is difficult to bring in line with that bid of fairness (and is not the best of the familie anyhow)

I originaly inserted Houdini as the author was the first to be man enough to sign this group of engines with his name (and I admit, today it is hard to ignore the best engine, but that came out long after I included Houdini!)! Same goes for Rybka. I don't like Strelka 2.0 too much, but the author is known AND Fabien (Fruit) even accepted it, I see it as some kind of reference and have no real argument against it. You mentioned Protector, why? The author is known and the source is available. Did I miss something?
Strelka 5 is (officialy) missing, but it is a rip off and the author once claimed here in that fora that he will purposly not obey the GPL (as an answer to my question). And as others it is not the best of its family and woudl be out again after testing. But for sure, that is my weakest point. I simply try to have some common sence here!

There are other Litto-Compiles out there where the author is known but I don't see a reason to test lesser engines as the best of that group is already in AND I am not willing to test one and right after that someone will tell me that THIS other version is 20 ELo better. Another argument is, that I dont want a rating list wich is poluted with many time the same engine (more or less). This would definately distort the ratings and noone with some knowledge want to have that!

Bottom line is: I try to make my list fair, honest and with some common sense!

Btw: It is interesting that the most quoted list basicaly all have this set of rules. It can't be that bad as other lists exsits and do not drive the known ones to extinction. If this will happen in the future, so be it ...

I hope this helps a little to understand my motivation.

Bye
Ingo

Moin Ingo,

you are being mislead by your own rules. :evil: :!:
The only thing that determines how useful a technically correct rating list is, is the extent to which it covers engines in common use.
If commonly used engines are missing on a rating list, the list has holes.
Rules cannot fill the holes.

Best,
Matthias.
My engine was quite strong till I added knowledge to it.
