Re: Muller, Hyatt, Schroder and other elderly

Most here are tired of reading how the old programmers feel. When these three have gone to shoot pool with St. Peter then the young and new wont have these same feelings and complaints. I wonder how the young and new will manage their tournaments. I wonder if the young and new will care about rever...

Re: Why don't we organize a World Computer Chess Campionship

Don't get me wrong, it would be great to see a proper chess WC. But it's very hard to organize, quite expensive and less worth it than in the pre-Internet past.

Re: Question for programmers

Parallel search is most definitely a non-deterministic algorithm, and does regularly produce different results. The time to reach a specific ply is almost always wildly variable, and sometimes event the score or best move changes. The above is a quote from a programmer. So I was wondering just beca...

Re: Question for programmers

Hi - interesting question but why does it need to be fixed? The implication is that a deterministic result is something of value. Surely playing strength or style of play is far more important. Does determinism have any intrinsic value? I haven't seen anyone post, "Stockfish got the same PV three t...

Re: Help with CLOP

As for how many games, it depends on a lot of things such as the number of parameters, ranges and how much accuracy you want. I typically tune 1 or 2 parameters and 10,000 games gives acceptable results so far. With more parameters you'd probably want at least 100k games. How did you come up with t...

Re: Help with CLOP

Just 2 more questions, if I may: 1. How do I make sense of the data? Do I look at the mean? (I have put in 4 values for tuning) 2. How many games should I let it play? Is there a limit, or will it just keep playing on until I say stop? On average how many games till it converges? 50K, 100K? *Curren...

Re: Magnus thinks 7-piece TBs won't be resolved in our lifet

... Just think how wonderful it would be, if any position with up to 11 pieces, is totally worked out to perfection! (I'm speaking from a little amount of observation and thought, that 11 would hit a goldmine, but that 10 would still miss it but also that 12 will not be necesary. It would be intere...

Re: Magnus thinks 7-piece TBs won't be resolved in our lifet

Magnus: "There are databases already for all possible moves with six pieces on the board, but I don’t think we’ll see seven pieces resolved in our lifetime." (When he says "our lifetime", I think he means his lifetime, so take it from that perspective.) I wonder what are people's thoughts on this. ...
