Re: Google's AlphaGo team has been working on chess

It's still sold. BrainMaker Professional for Windows $795 :lol: Very nice you know that one too! I was already playing with that package 25 years ago. I still have an old version 'BrainMaker v2.52' (written in Borland C) somewhere on my NAS. The floppies it originally came on are long time gone. Ed...

Re: Google's AlphaGo team has been working on chess

That is a start for sure -- proving a NN evaluation could be competive or even much better than a hand crafted evaluation function. The latency of evaluating the NN can be countered with a combination hardware (GPU/TPU) and software (async evaluations) which is what Google did for AlphaGo. Giraffe ...

Re: I can't believe that so many people don't get it!

They mean normal nodes per second. It is not easy to compare hardware that is very different. Depending on what feature you compare you can make one or the other look better. Stockfish would probably run 20 times slower on the hardware AlphaZero was using than on the hardware it got . It is irrelev...

Re: Cerebellum analysis of the AlphaZero - Stockfish Games

I calculated the AlphaZero games and added them to Cerebellum, which took some time because Stockfish naturally needed very long calculation times and many added nodes to finally get the (most likely) correct results. http://www.zipproth.de/Brainfish/Cerebellum_AlphaZero.html I thought about a way ...

Re: In chess,AlphaZero outperformed Stockfish after just 4 h

I don't care that SF lost, it's totally irrelevant in the light of the huge claim by the Deepmind company, the alleged 4 hours self-play, quoting the document again: without any additional domain knowledge except the rules of the game . Have you already let it sink in what is stated here? No mobili...

Re: I can't believe that so many people don't get it!

"Monte Carlo search does not use a tradition eval as we know it, so mobility, king safety etc. are irrelevant. It uses a struct to hold info likes wins, losses, draws, win %, etc., then simply references accumulated data for the current position to select the move with the highest probability of wi...

Re: I can't believe that so many people don't get it!

But is that correct? There is evidence that they keep a learn file with wins, losses, draws and a percentage chance of winning. Are there enough neurons to remember millions of these stats or is there more to it? In a human brain data storage and neurons are synonymous but in a computer brain neuro...

Capablanca games to me are clean and efficient, applying exactly the right amount of effort, no more, no less, to achieve the result.

His calm, deft parry against the inaugural Marshall Attack is a case in point.
