Re: An objective test process for the rest of us?

A deviation of 2.5*sigma is one-in-a-hundred, so if you post 64 mini-matches it is not at all significant if it occurs once. A deviation of 4.5*sigma is a one-in-a-million event. Could the apparent correlation in the data be related to favorable/unfavorable memory and cache issues mentioned by Bob ...

Re: Ali Baba and the 40 positions

Scrappy has been on some but nobody plays it. I've noticed that programs that haven't played in a long time won't show up for example with "who C2000-9999" because their ratings are out of date. Only after the program satisfies the [need] quota will it be displayed. Some people check this way for a...

Re: Ali Baba and the 40 positions

would personally rather see games against real humans. I have seen 2000 humans stomp 2200 programs when the 2200 programs make blind positional mistakes and don't understand passed pawns or long-term kingside attacks, and go pawn-grabbing instead... I suppose I could try Crafty with just material a...

Re: An objective test process for the rest of us?

What about the variance per column aka sample position? Here is Bob's data transposed. The first two rows here are the first Silver position, where 01: Crafty playing white and 02: Crafty playing black. 01: ------------------=-----=--==--- -26 02: ++++++++++++++++=+++++++++++++++ 31.5 03: -=-==----...

Re: Questions regarding the Election and Nomination Process

... But putting words into my mouth (or anyone elses for that matter) is simply unacceptable. In the extreme. I agree that would be extreme. However, I've not seen words "put into" mouths but rather "taken out of" mouths (so to speak). Always characterizing such deletions as "putting words into mou...

Re: Questions regarding the Election and Nomination Process

That idea is so very basic to all computer chess events, that saying "Oh, he didn't know, or didn't mean to hurt anything" just simply does not cut it. If a guy lives by himself deep in the jungle somewhere, and then makes his way to civilization at age 30 and immediately kills someone to take thei...

Re: Something 'Fishy' about Strelka

Using IdaPro to examine the binary, it's not a chess engine. It's a decryption engine sitting over a giant block of data. Seems pretty strange for a chess engine of 1.4 MB to consist of 95% data, a decryption engine, and a small set of Winboard commands. I guess that Uri was right. Perhaps there's ...
