Houdini - Cluster Rybka encounter....

[Dr.Wael Deeb]

Houdini is not that brilliant as many think.....

It's just that Rybka is making horrible positional blunders and is getting squashed by Houdini.....

Something is wrong here,I don't know.....

Is it a bad special settings for the match

Is it a bad scaling and not getting the optimal communication with all the 64 processors that Rybka is using

Is it an experimental version of Rybka that is palying

Again,after watching the second game,I am pretty much convinced that Houdini is not that ingenius chess entity as much as there is definitely something wrong with cluster Rybka.......

the match is not about houdini, it is about rybka. we already have an excellent idea of houdini's phenomenal strength. we have yet to see the 'strongest chess entity in the world' really tested. what this match is showing to me thus far is that rybka.exe has NOT made significant leaps in progress since the release of rybka 4. this is a pretty huge.

Exactly one of my points of vview related to this issue....

Then why are they charging people high fees to rent the cluster when you can simply get a reasonable i7 system with enough ram and buy the latest Houdini

This is a terrible advertisement for the Cluster Rybka.....

But then again,I don't think the top 100 human grandmasters are even following this event....

I think that the myth of the better version of Rybka in the cluster is just that, a myth.

Rybka cluster plays almost exactly as Rybka 4.1, and it has the same shortcomings. I've seen many times Rybka getting "lost" in similar positions as the one of the 2nd match, and these things you cannot avoid by simple hardware, it's impossible.

The fact is: Rybka is now 3 years old eval, and, differently from what many people think, the worse the eval the more you will be in trouble at slow TC with the less help (in this case the less lines in a book) you have.

[Lavir]

This is a terrible advertisement for the Cluster Rybka.....

And in fact why do you think Lucas or Vas never wanted to sponsor a match like this?

They could easily rent the Cluster (at full power) for free, and instead they have people pay for it to play the game. If they did know Rybka would win easily, they would gladly rent the Cluster for free, since that would be the best advertisement for them, but since it is the contrary...

[yanquis1972]

but given that, the implication that vas has essentially abandoned work on the software end of rybka is a terrible blow to computer chess...still some games to go, still only a handful in total, but this match really could be seen as the end of an era when it's over.

on to houdini, stockfish, komodo, & critter.

Are you sure?
If Rybka plays any move better without cluster, OK. But if not, and cluster makes it slightly stronger, then it is NOT something wrong. It's just what it is. Then again, maybe it is that you don't want to say that Houdini is great.

Houdini is not that brilliant as many think.....

You are a funny guy, you have strong sympathies/antipathies for persons and project them on engines.

Houdini 3 is pretty brilliant, even simply by not showing a single crack in some 180 moves played against Cluster Rybka. Which Cluster Rybka is at least the level of kibitzer Rybka 4.1 engines on Playchess interface Let's check, probably much stronger. A complete mauling until now, and importantly, from the starting position.

Hi Doc,

isn't Cluster Rybka set for analysis purposes and not for playing against other programs?

Settings would be far for optional in such case.

Are you talking about only the now famous 42 ... a5!! move from the following game, or is there a match going on somewhere between these two chess-playing entities?

Thanks
