Komodo 5 release now available!

[Sean Evans]

Komodo 4, not sure why they have not released Komodo 5, now available for the iOS under the name Chess Legends:

YouTube Video

App Store

The program has to few reviews to give it a rating. So let's get together and give the program some positive reviews to allow a proper and well deserved rating!

Enjoy,

" If you can spare the computer time, it would be interesting to rerun your match with some conditions changed, for example 2'+1" instead of 1' + 1", or ponder on, or 128 hash size. Aside from getting more sample size, it might show that we have a problem with small increments or with ponder on or with small hash for example, and if so perhaps we can do something about it. "

I'm running same test with ponder on now. Did switch to F11 , couldn't find a way to do it in F12.........

K5 has lead all the way , but it has been close so far ....
117 games = +40 , -38 , =39
I suppose it will all be small sample / marg error stuff , but is what it is........

update after 300 games

I'd be more than happy to run more tests .
Let me know what you'd like to see next.

I guess I'd like to see 2' + 1" next (ponder off). I have a theory that small increment compared to base time is bad for us; if this is so then we won't do so well at that time limit.
Also please comment on the opening books used for the test. How deep are the lines, and are the openings mainstream theory or offbeat?

Thanks for the link Sean. However, sadly, this app is JUNK! The engine always moves instantly, regardless of the selected time control. The gui is terrible, and offers very little. I can see why it's only .99, even that seems like a bit much for this. Don and Larry could have found a better partner for their fine engine. IMHO

I am using the klo_150 openings , mainly because I DL them a few yrs ago , and got them to work. No idea about the nature of the lines , and to be truthful , wouldn't be competent to comment.........

I tried to get Sedat's Perfect Book to work , but I'm having problems getting the correct file format , or folder location , or some combination. Seems to load to play a game , but not for an engine test.

Would be happy to try another OB , if someone can give me some pointers.

PS , Houdini starting to pull away.......

140 games , H leads +48 , -43 , =49

Hi Tom, maybe I missed it, but how many cores is Houdini using in this test?

Thanks,

Maybe it is just me, but I have no clue how anyone could complain about anything you and Larry have done.

Hello Tom,

Thanks for your interest,but i never noticed such problems

Are you sure that you are using the right compatible book format ?
For example,if you want to test the engines under Fritz GUI,then you need to use the Perfect 2012a.ctg (e.g you can find it in Fritz folder)

And here is my latest public release,which is compatible for 8 Chess GUIs:

-Aquarium
-Arena
-ChessGUI
-ChessMaster
-ChessPartner
-Fritz
-Shredder
-Winboard


You can download Perfect12a books (Full Package):

Btw,(due to many requests) very soon i plan to release Perfect 2012b books


Best,
Sedat

Hello.

I can not catch up in which way it is fullfiling the promise to get Komodo 4.1 SP for free by K v4.0 buyers?

1. There is not 4.1 V.

2. It looks that v.4.0 buyers have to pay next time and buy version 5!

Rgds Hood

If you have Komodo 4 it will cost you $20 to get Komodo 4 MP - that was the promise.

Since we are not going to release Komodo 4 MP or 4.1 MP you will get Komodo 5 MP instead by paying only $20. Pay the $20 and you will get Komodo 5 SP now while you are waiting for the MP version.

So it's up to you - if you have already purchased Komodo 4 you can pay $20 and get the SP now and the MP for free - or else you can wait and pay $20 later for the MP when it's ready. We believe this is a much better deal for you than what we were going to do.

Maybe it is just me, but I have no clue how anyone could complain about anything you and Larry have done. If a stats guy was to take the elo increase from version 4 to version 5 when it is determined, and then factor in the price you charge, the average charge for every 5 elo increase would have to be the lowest in the history of computer chess. Or just translated: Komodo 5 is the best "bang for the buck" - and I cannot even find a close second.

(Please, no one be a big enough idiot to respond to me by throwing a freeware up to me in comparison. I have had my quota of the brainless for a few days at least.)

I disagree here.

I can see 102 elo improvement in the CCRL 40/40 for
Rybka3 single processor



Rybka 3 64-bit 3077 +9 −9 73.9% −185.0 29.8% 6034
Rybka 2.3.2a 64-bit 2975 +8 −8 67.8% −126.7 37.0% 6088


Rybka3 single processor relative to Rybka2.3.2a gave more than 100 elo improvement at 40/4

I do not remember the exact price of Rybka3 single processor but I will not be surprised if the price per elo improvement was lower than the case of Komodo.

Sigh. OK, Uri-I was wrong. I did not think about Rybka- possibly because I have no idea what he ever charged for anything, as I got everything he ever put out free of charge. And really I have no excuse still- because I have been adamant about the huge, huge increases AFTER HE HAD STUDIED FRUIT- even challenging any programmer to take it all- completely gut Fruit- and even come up with 50% of the strength increase he did. (BTW, after studying Fruit- his next version was a 221 elo increase!) No takers, obviously. More "all talk and no show" from the Rybka haters. Which was all they were ever good at anyway.

(The idea that anything Vas took from Fruit helped him with increases in strength that amounted to much of anything has never had any basis in fact. Only in the dreams of the jealous)



Best to you,

OK, now we're getting somewhere! That book is only 4 moves (8 ply) deep. I think the testing organizations test with books considerably deeper than this.
I have believed for some time that Komodo was the best engine in the opening phase of the game. If much of the opening is played by the book, this advantage loses its value. So I expected that the deeper the books used for testing, the worse Komodo would look relative to other top engines. Now there is solid evidence to substantiate this.
So it seems that with minimal book help, Komodo is fully competitive with Houdini 2 or even superior, even at fast blitz levels, but when the opening is played by the book Houdini 2 still has the lead. Of course this is not yet proven, as their are other variables in the various tests, such as ponder, type of time control, AMD vs Intel, and average time per game. So we need more data, but at least now we know what we are looking for.
Any info about average number of ply in book for each testing group would be helpful here.
