Buying a refurbished computer

I think to buy a new computer and I wonder what is the elo of stockfish and lc0 for different prices of hardware. Is there a table for comparison that give price and elo estimate for both? The "buying a new computer" thread inspired me to share my experience with refurbished workstations and have b...

Which might look some thing like this:

Move ranking Score = (Average game score for this move) + SQRT(Constant1*LOG(Total number of games played from this position)/number of times this move has been played).
Looks as something to try, what initial number to feed "Constant1" with?

Re: Ferret 1.00 v258 - program from 1995

Steve Bruce Moreland also wrote a WB-compatible engine, Gerbil : http://rwbc-chess.de/download.htm Has anyone tried it? CL Looks like a book download only. I no...

Re: For data lovers only

All the downloads failed at the very end for me (using FireFox derivative PaleMoon). But I did something underhanded to find the absolute address and downloaded them using wget (I was nice, one at a time). I know you want to enforce your own interface, but I figured you would not get mad since I tr...

Re: For data lovers only

All done... In total 25.6 million annotated Stockfish games. Say average game length is 60 moves, we get: 25.000.000 x 120 = 3.000.000.000 positions for NN training or other purposes. If you post a link, I will be grateful to greedily snatch a copy. It's on the link in the OP - http://rebel13.nl/do...

Keep the volume reasonable. Maybe I will do 2100 and 2000 later.
Or 2400 and 2500 for smaller download sizes.
Once you have the human database of 3.784.887 games installed you can extract from that database higher elo rated database such as 2300, 2400, 2500 etc. with SOMU 1.5, see the page.
