oldie but goodie

Post by MikeB »

Today's programs are not much faster than those from 11 years ago, some even slower. Except for the Sting-v8 which was amazingly fast in this position - about 3 seconds on my Machine. Rybka was pretty fast with this position 11 years ago.

Latest McBrain ( SF based, not yet released) was about 2 minutes, dev-SF and K11 also struggle with this now..

output below is from xboard, which goes from bottom to top ( opposite normal output from the console, top to bottom ) - which makes sense with the GUI, but in case if you were wondering why...

The UCI version of chest solves it instantly, if you let it lookup search parameters from its database.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I do not know based on what you decide that today programs are not much faster than those of 11 years ago.

If it is based on some sacrifices then tactics is not only sacrifices.

Compare time to find a forced mate against part of the pieces and I would like to know if there is a single 11 years old program that is faster than stockfish.

I can add that stockfish with 3 cores and 1024 mbytes hash solved it on my computer in less than 5 minutes

Re: oldie but goodie

Hi Uri,
Uri Blass wrote:I do not know based on what you decide that today programs are not much faster than those of 11 years ago.

If it is based on some sacrifices then tactics is not only sacrifices.

Compare time to find a forced mate against part of the pieces and I would like to know if there is a single 11 years old program that is faster than stockfish.
I thought Ruffian solved this quickly, and I was right - quite a bit faster than Stockfish on 4 cores. These were run on a 2.6 GHz i7.

I wouldn't be surprised if other "oldie" engines do well with this one. The modern LMR approach will often kill off these long threat based mates.

Re: oldie but goodie

I guess the reason is that modern programs prune more aggressively, and that means they may overlook something more easily. But on average, it gains ELO.

DeepShredder 13 with 6 cores and 2 GB hash (7600 kn/s) fails to solve this position. It sticks to 1. h5 even when reaching depth 34/62 after 7:43 minutes. Obviously, the mate would be in the horizon, so it is a pruning issue.

If I play Qxg6+ Kxg6 and start the analysis again, then DS 13 finds the mate in 14 at depth 25/69 after 12 seconds.

Now if I take back the moves and then start analysing, it finds Qxg6+ with mate in 15 after a second.

Clearing the hash tables and starting the analysis again has the same result as originally - DS 13 fails to find the mate.
