told you R4 would eventually start to pull ahead,i use both in corr chess at much longer T/C's and know which is more accurate.could take you hundreds of games before you believe me. :smile:

I would have to say that Stockfish has improved its game-like you say it could take hundreds of games before we see how little or how much.

I've asked Dadi to lock this thread down and I will no longer post here- I have no intention of stopping the original Match on the Edge- I would have liked to post just the high-lights here but that is obviously going to be impossible.

I have been using an Aquarium beta build in presenting the pgn's on the Edge-where I can see the results of each build and where inherent information of each build can be explored- it has yet to be finalized.

I thought while I was testing these builds in a Match format it would be nice to share some of the highlights of these games presenting here a easy to read pgn format until the Optional pgn formats have been finalized.

What is the Hardware used ?

By Arrière Pensée (Gold)

Date 2010-10-08 08:43 Edited 2010-10-08 08:56

> What is the Hardware used

i7 930 overclocked to 4009 MHz on a P6x58D Premium - with 12 gigs of ram. Just by way of info- the i7 930 runs hotter than the i7 920- Originally, I was using a Corsair H50 to cool the cpu and was clocking easily at 4200 MHz - but the H50 stopped running within three weeks of having it installed. Luckily, I was present viewing the screen and caught the temp going through the ceiling and shut-down the system. I ended up installing a Cool Master V8 which keeps the temp down to an average of 58c on each core at 4.MHz. I don't see any reason to push it up from 190.

I do think that Stockfish has improved it game in long time controls- Stockfish seems to be giving R4 competing better than Stockfish 1.8 did. Although, I don't have the stat's to back that up.

I'll put out a compressed file of the games up to game 24- probably Sunday. For anyone who wants to look at all the games to date if it is of any service. I hope to run this match through to at least 40 games if not 50.

By Arrière Pensée (Gold)

Date 2010-10-10 16:09 Edited 2010-10-10 16:12

hi Indrajit,

Okay! I was well into the match when Tord Romstad, Marco Costalba & Joona Kiiski, introduced Stockfish 1.9.1. and here is what they stated:

"What's new:
This is just a bug fix release to restore chess960 support under some GUIs.

There is NO functional change and NO speed change, so absolutely NO ELO change from 1.9 and people that has already tested 1.9 could safely keep test results when swithcing to 1.9.1."

I did not want to interrupt the match to make an updated engine change (didn't want to risk ending up creating another match by accident.).

Thank God! The update had nothing to do with any changes in Stockfish 1.9. x64.

Chow

pS

If there were any performances changes-I would have to stop this match and start all over again! :eek:

By Indrajit (***)

Date 2010-10-10 19:26

No no... don't stop...Even if there are no functional changes, it seems to be holding up pretty well against Rybka 4. And thats what matters most :twisted:

I plan to have matches between stockfish and hiarcs. Though I don't have powerful computers to test.

There is one other comment I'd like to make-

So far Aquarium's performance has been "Flawless" - the new interface for Match/Tournaments is a real joy to work with- the entire design set-up is absolutely great, and makes running this match a lot of fun.

New Feature of Fritz 12! And, don't tell me to get Fritz 11!

Tweaking Fritz - PART 6

The biggest visible feature of this mode is that the area surrounding the chessboard will turn bright screaming red whenever the chess engine makes a move.

And you're complaining about two little boxes?

Game (25) is in an endless protracted draw-but, I refuse to interfere and am going to allow it to play out. It has already taken up a good part of the day and probably will take up a good part of the night as well- black still needs to play the same opening.

Edit: I did interfere and adjudicated the game. The only game in the match so far that had to be adjudicated.

Robert,you have to trust me on this.R4 is much stronger than SF.on Hiarcs forum i had to correct their AN in a match game against Erdo and Zappa(Rondo) if we had followed SF we would have lost the game.i am again talking about 48/hour move.these games of yours are misleading although of much interest to me and others.i think my record on Rybka forum speaks for itself in corr games i have won last 5 out of 7 the other 2 being draws. :smile:

By Banned for Life (Gold)

Date 2010-10-11 00:36

I am not convinced by your argument, which seems to be based on a sample size of 1 game. I believe that R4 is a little better, meaning that the number of reasonable positions that it plays better than SF is higher than the reverse.

And there are plenty of positions that Stockfish plays better than Rybka 4, I can testify from my corr games even though my record isn't as impressive as Paul's (don't even know what my record is :yell:

> Robert,you have to trust me on this.R4 is much stronger than SF.

I don't think I'm wasting my time- and I do think it is interesting to see how both engines handle the games played- How else are you to measure the progress and development of a chess engine?

> i had to correct their AN in a match game against Erdo and Zappa(Rondo) if we had followed SF we would have lost the game...

That may very well have been your experience- and that was Stockfish 1.8. -

What! We're susposed to automatically determine without test or trail that any version of an engine is a waste of time because it didn't flat out beat R4 in a previous verision?

I'll continue on with this match until it is finished and let others determine whether my efforts were worth it or not.

Let's put it in these terms- It is a start!

The testing is certainly worthwhile, showing that at reasonably long time controls SF1.9 can beat Rybka from positions where it will get draws with reversed colors. Although the number of games is still very small, it seems unlikely that R4 is much better than SF1.9 at this point.

What I am looking at is in matters of degree! It isn't a matter of either/or as Paul is terming it.

After 24/ and now 8 days of running this thing -I don't handle very well someone telling me, " what are you wasting your time for R4 is stronger then SF." I want to see- get a sense of just how much stronger R4 is- and I would hope that some indication of that will come out in these games.

And this is going to go on possibly for another 7 days? Unless the Development Team saves my ass by coming up with a build that will wipe out the match currently running in a new install. Haahahhaha! :eek:

I had to step in and adjudicate this one. Please be advised that the colors represented in the results bar are NOT calibrated correctly on my lcd. I have an ips paneled lcd and that demands calibration out of the box. I haven't the bucks yet for the calibrating tool-for give me.

What you are saying is that the Stockfish not only isn't stronger than R4, but sucks at analysis as well, which is implying that the engine is totally worthless. :yell:

I find both of those engines handicapped when it comes to analysis; R4 by bugs which cause MPV and even SPV to fail on a regular basis, and SF1.9 by a hash structure which doesn't retain much information when you step forward or backward.

I'm happy about it though, knowing what to do with the engines as they are gives me an advantage against people that don't. E.g. people that aren't used to rely on exclude moves.

When using R4, I end up using techniques eerily similar to techniques I used to use with persistent hash to recover from R4 losing the bubble (indicated on my system by kn/S going over 700). This leads me to believe that Vas' hash concept may be flawed, rather than this just being an implementation issue.

I don't have any workarounds for SF1.9 going brain-dead when I move forward or backward.
