Stockfish, Please correct your depth and node count

Post by kgburcham »

According to analysis below:
Stockfish depth 31 in 16 minutes 10bn 10971kns +1.77
Rybka depth 21 in 58 minutes 1bn 500kns +1.88

Since some say it does not matter what programmers report to the users and purchasers----cant we all agree to adjust these Stockfish numbers to reflect Vas adjustments to his program???
This would be more accurate:
Stockfish depth 7 in 16 minutes 333mn 500kns +.60

Rybka is known to alter real depth and node count....now you are asking that SF should print fakes depths and node counts just to be as faked as Rybka's output ????

FYI SF output regarding depth and node count is correct. It means that this is the _real_ maximum depth reached and the _real_ nodes/s calculated. Everyone looking at the sources could confirm you this.

Hi Marco,

I also took the initial post to be a joke aimed at Rybka, though I must admit that it took me several readings before I realized this.

I thought the intention of the original post is to tell that he just spent lots of money on uber powerful computer.

Yes.... All jocularity aside..... I think every purchaser of a program or user of a free program would greatly appreciate-I reiterate would greatly appreciate -let me state unequivocably -greatly appreciate in no uncertain terms a program that does not- I repeat does not obfuscate the node count or depth. :roll: There. I feel better now.
