Re: A Book For a Vintage Program

I'm looking for an opening book for a vintage computer program from the late 1970s. I'm guessing this program has not played any public games since 1978. It will likely not search deeper than 9 plies at human tournament time controls. The program will not be a giant killer but it might be a novelty...

Re: On-line engine blitz tourney October

Surprisingly rofChade ended above the two Stockfish derivatives Honey and Belfish and won the tournament. Goldbar was very happy that he managed to get a draw in the last round against Honey, rofChade owes him a beer for this accomplishment. Nightmare unexpectedly lost from CoronavirusChess in a we...

Re: Unsupervised reinforcement tuning from zero

Of course it is. You need to start with some code that can distinguish features. And a bunch of games with result. Loop: Train/tune (what’s the difference?) Make loadsa self-play games Round and round you go And so the only real difference between handcrafted evaluation and neural networks is handc...

Re: Unsupervised reinforcement tuning from zero

yes... it was done before, and it works... but you usually get better results when you start from good values, because it is easy to get trapped in local minima, so you get sub-optimal values for your eval function... the framework that is used most often right now is so-called "Texel" tuning and i...

Re: Why does TCEC use unbalanced opening?

I'd like to see TCEC return to using balanced openings, with perhaps a 6 moves per side limit. And 96 draws out of 100. Do you want the best quality chess, or just artificial entertainment? Best quality chess is agreeing to a draw right after starting the clock (both 32 men tbs). And frankly, I can...
