Aug-03-07  Akuni: How did a computer get an Elo rating?
Premium Chessgames Member
  WannaBe: Just like a 'regular' human being, by winning, drawing, and losing...
Aug-04-07  rover: Naum isn't a computer, it's a chess engine. Its performance depends on the hardware it runs on.

Chess engines or engine-computer pairs don't get FIDE ratings, although if they play a tournament against human opponents it is of course possible to calculate a performance rating. Non the less no engine-computer configuration played enough games in human tournaments to get a reliable estimate of their rating.

Some computer chess enthusiasts play chess engines against each other on standardized hardware and use the results to assign ratings. Such ratings are good indicators of the engine's performance in computer matches but not so good in predicting their performance against humans. And of course they have nothing to do with ratings assigned by FIDE or the USCF.

In any case I don't think it is a good idea to quote these ratings here since they might be confused with FIDE ratings.

  Domdaniel: More to the point, what's an engine rating doing in CG's list of top players by rating (<database statistics> page), which I think has been a comp-free zone until now.

Of course engines can be rated by playing games, and naturally those results are statistically valid -- but I'd rather see humans and engines separated in this case.

Sep-09-07  fndmiranda: Yeahh!

I got it!...a draw against Naum2.0!

Why the engine dont stop my draw move?Whats wrong with Naum2.0?

  Domdaniel: <fndmiranda> Congratulations.

<Why the engine dont stop my draw move?> Who can tell? Engines move in mysterious ways, and often have small glitches where draws are concerned. They tend not to 'weigh' the draw possibility in the way a human would, or choose the right moment to stop playing for a win and aim for a draw instead.

Sep-15-07  fndmiranda: Yes,thank you.Im always crushed by strong engines like Rybka or Hiarcs11.Im feel very happy with this game lol. I have a chess problem here,i never see a chess engine find the right move,here it is:

White:Pawn on d2
King on d5
Knight e5
Knight f5
Black:Pawn on c4
Pawn on g2
Pawn on h4
Pawn on h6
King on h5
"White moves and draw"-Can you find the move?Rybka or other engine miss it,even if you set infinite analysis.Good Luck.

Sep-15-07  Tomlinsky: I don't see a drawing line for white in this position...

click for larger view

Black wins in all variations with best play as far as I can tell but would love to see analysis that proves the draw.

Sep-15-07  fndmiranda: Hello Tom!
Its incredible,but thats it:White plays and draw the game.Its a magic move.If a computer find this move,the human chess is over. Try again,and latter ill put the answer.

  whiteshark: <fndmiranda>: GREAT study by Bething, a steely cobweb - indeed engines don't find it!

Solution posted here: Max Bier

Sep-15-07  fndmiranda: Yes.
The solution is:

1.Kc6(to avoid the queen checks)

2-Nxh4(Black king cant take)

The knights defend each other and one of them defends the d2 pawn,in turn the d2 pawn defends the c3 square,stoping blacks pawn.

All that black can do is check the white king,and draw by the fifty move rule.

Sep-15-07  Tomlinsky: PING! That's a killer <fndmiranda>, thanks. :)

  whiteshark: <Naum 4> target release date is Dec, 15th !

= ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘ = ♘

Estimated ELO improvement is between 80 and 120 points.

May-24-09  Dionyseus: As some of you may have heard the author of Naum 4, Alex Naumov, has decided to end major development of Naum, claiming Rybka's author is too good as his reason.

This is very bad news because Naum 4 is the only engine that really seemed poised to challenge Rybka's supremacy. Naum 4 is according to the major rating lists CEGT and CCRL the only non-Rybka engine that is stronger than Rybka 2.3.2a.

So consider that for a second, if Alex Naumov had the ability to time travel and went back one year, his engine would have been number 1, at least briefly.

Dec-17-09  notyetagm: <RandomVisitor: At 40 moves/120 minutes tournament time control, here are the top engines running on quad processors: CEGT list:

Rybka 3 - Elo 3166

<<<Naum 4 - Elo 3105>>>

Rybka 2.3.2a - Elo 3070

Deep Fritz 11 - Elo 3014>

Wow, what is this <Naum 4> engine?

Jan-24-10  Red October: free update for Naum 4 customers, Naum 4.1 has been released :)
Jul-30-10  Xaurus: TCEC Tournament 1 has started.

Apr-21-13  mrandersson: Shame what happened to naum engine. Its a great engine and it had a style of its own i thought. The last super original engine maybe?
Dec-17-13  mrandersson: Hey does anybody know were you can get the new version of naum the 4.6 one that's been played in comps on the net?
Sep-29-14  mrandersson: After a few months naum 4.6 had been made a free download great news.
