1) Conventional node speed display - please Vasik!
2) Faster updating of search info: when analysing game back-and forth sometimes Rybka don't display anything
    new and speed is 0 kn/s.

I think these are easier to implement than +50 rating points.

I thought 1) was measured properly. isn't it just that rybka has a low kn/s?

Have you ever heard of Strelka? Or this post?

relevance of strelka?

It plays almost exactly the same as Rybka 1.0 and counts nodes in a normal way according to Uri. A lot faster than Rybka 1.0, though.

#2 will be in Rybka 3.0
#1 don't seems all that important to me...

Ditto.

Yes, Vas suggested an option where you can set a very high node output so every GUI will crash. That's sounds ok.

I agree with you Jouni. 
 
I believe that it's better that the new Rybka 3 can count their nodes in the known conventional mode.  
The faster updating of search info also should be fixed as soon as possible and I think that Vas it is very aware of this.
 
Although, make a stronger Rybka it is the principal thing here and it should be this way always. I think that Vas knows that an improvement of +50 points in the new Rybka version can be possible, but I think that still is too soon to speak about this. Perhaps Vasik can tell us a little more about this.

Gambito.

I think that the node count in Rybka is specially designed to measure the effective speed improvement of increasing cores and going from 32bit to 64bit. If Rybka counts twice the nodes but only 50% of the new searched nodes are useful, then it will display a 1.5 improvement (Instead of the conventional 2.0) accordingly.

I think that it's already on latest Private Beta, that Rybka sends info to the gui every 6 seconds or so, so you know that Rybka is still working.

In the Fritz GUI, you can see that Fritz 11 sends some info every 2 seconds. I like that and I think that it's even a better time interval. It doesn't care, how much time the engine was analyzing the position, you can see the engine will be always thinking. 
Of course it's important to implement this in Rybka 3; that it should be made, should be made.

We're still working, Rybka 3 is still at least three months away.

I want you to tell me what you mean by Conventional node speed display.

As far as I know I thought because Rybka has implemented lot of chess knowledge the Node speed is really low.

Prem

Not necessarily.   
       
Other engines have more knowledge than Rybka and are even faster. However, nobody can assure how counts nodes each programmer.
But Rybka counts nodes too different to most.

The reason why i say Rybka has best knowledge implemented is by
1.File size of EXE or the engine file.
2.The related node speed.

We have an excellent solution for #2 now - after you see it, you won't believe that you ever lived without it :) I'll explain it in detail after we release.
