Hi Fauzi,

I hope this link will work well. (Anyway I have found 19 downloads till now).

Best regards,

Tom.

[fauzi]

yes this one works, thanks Tom, anyway I think You found 19 downloads because this is not the only forum You post Your tests, so maybe in another forum You posted the link right but here the full link was missing thanks alot for your effort

We have/had an ID issue. Stockfish 041213 = April 12, 2013 to me. Best format is US military, 04Dec13.

In any case, my bad.

Hi Bobby-

"month year day" is used in the US (as you well know),
but here in Europe, most (all?) countries use "day month year"

(which actually kinda makes sense: periods of time increase naturally as you read from left to right)

regards-
Norm

Norman,
SF's file ID system gets even more weird:

The version at the site - month, day, time, year
The downloaded file name - year, month, day, X(mystery ID ?)
The file name shown in (Fritz) UCI - day, month, year

All I'm saying is, there's better ways.

Extreme equality between these three engines, with clear differences in function of the time control.

Extreme equality between these three engines, with clear differences in function of the time control.

Chess Engine Rule #1: The precision of the analysis is determined by time available per move, or by the fixed calculation depth you allocate.

Chess Engine Rule #2: The precision achieved by each engine per second of analysis varies for each engine.

The testing confirmations here of H's dominance in TC <30+ are now too numerous to count. However, such is not the case in TC >60+ where H appears to be #3.

Chess Engine Rule 3 (mine) = The speed of the computer is very relevant.

Example: If a computer A) has a Fritz Benchmark of 20,000 KNS and computer B) has one of 1,000 KNS , the precision of the analysis will be higher in a 1 minute per move for A) than in a 10 minutes per move for B).

IMHO the relevant point is therefore not the time avalilable per move, but the number of nodes calculated per move, taking in consideration not only the time available, but also the speed of the computer.

If I make a fussion between my two latest tests –same engines and same time controls- we get this

OVERALL PICTURE AFTER 960 GAMES:


1.- Stockfish 091213SL 64 SSE4.2L 242.0/480 50.42%
2.- Stockwood 061213 64 SSE4.2 240.5/480 50.10%
3.- Stockfish 071213 64 SSE4.2x 239.0/480 49.79%
4.- Houdini 4 x64 x CT0 238.5/480 49.69%

Under my testing conditions the differences among these four engines are very small indeed.

Regards,

Tom.
