Komodo 5 release now available!

[MM]

If i am wrong i will apologize with Don and larry but i think this version has (if) a very little improvement compared to Komodo 4, i would say around 10 elo.

If it is so it is a very sad day for all computer chess lovers and the triumph of Robert Houdart.

Best Regards

We have MANY tester who have verified that Komodo 5 is much stronger than Komodo 4. This is based on thousands of games - and our own testing is showing over 30 ELO at 2+2 on very fast hardware - roughly equivalent to the IPON time control.

So I trust our 30,000 game sample much more than the 700 game sample - although I admit this is disappointing so far.

4448.00 and 4452.00 are very close to Komodo 5 -hardly any differences and Komodo 5 is just a better compiled version of these.

So let's wait and see what happens.

Note that what you see live, is Shredder's Elo calculation which AFAIK is based on, or at least similar to the EloStat calculation. But the IPON rating list itself is calculated with BayesElo, after a test has been finished. This could result in a +/- difference of some points, relative to the intermediate result on the live page.

Isn't it possible the AMD platform used by IPON needs a different Komodo 5 compile ? I may be mistaken but wasn't this an issue with earlier versions as well ?

That is possible, but I don't expect it to make 30 ELO of difference. It is optimized for modern Intel hardware so I would expect it to run at least slightly better on Intel.

Since we are currently showing +36 elo for the actual release version over Komodo 4 after 3000 games by our network of (mostly) independent testers, against Houdini, Critter, and SF, if the IPON results end up way below this we need to find out why. The most likely suspect would be that we are doing something wrong relating to pondering, since we test with Ponder off and IPON (as the name implies) tests with Ponder ON. Another possibility is that the relatively large base time (relative to increment) in IPON (they use 5' + 3", we use 2' + 2") is unfavorable for K5. The AMD platform of IPON could also be an issue, we optimize on Intel. We'll have more info once the CCRL and CEGT tests come in for comparison.

A few people have tried to download from the site and just get Komodo 4 instead of Komodo 5.

We are doing something different this time - you will get an email with a temporary link - which you can use to download komodo 5. But I have had 3 or 4 reports of the email not coming - as it turns out the email MAY appear in your junk or spam folder - so check there if you don't receive it withing 5 minutes or so.

For what it is worth it has been almost 5 hours since I purchased Komodo 5 and still no email for my download link. Looking forward to using the engine,

thanks!

Tom,

I think you did get an email - the system shows that an email was sent out to you - please check your spam/junk folder. Several have reported that email is going to their spam. If I can figure out why that is I will try to improve the construction of it so that it is less likely to go there.

If you still cannot find it, send me a private email and I will make sure you get it.

Hi Don,

I have been checking both my inbox and my spam folder and nothing has come thru. I sent you an email as you requested.

Thanks!

Hi all,

Komodo 5 is running for my LightSpeed-rankinglist. After 1800 games (of 9000), the score is 6% better than Komodo 4 (+40 Elo). Final result hopefully sunday morning here on talkchess and (german) CSS-forum.
