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

We have been doing the math of these 4 TPU'S before. Even Mark Watkins [BB+] estimates AZ vs SF as: but this does tend to indicate (at least) a 100x hardware edge for AlphaZero, possibly something more like 1000x or more. Faulty math...

Re: AlphaZero Chess is not that strong ...

Isn't the "doubling time control" gives +50 elo"-statement from ages ago ? Does it still hold today ? I don't belive it :D Is there any statistics from Komodo,Houdini, SF on how well they do with double the time ? Search for "Elo doubling" in this forum. Several of us have investigated the Elo diff...

Re: AlphaZero Chess is not that strong ...

For traditional engines, how many extra Elo points does an extra ply of search add to its strength? I thought 50 points, but that's from memory. It could have been 30 or something entirely different. If AlphaGo had a x16 hardware advantage (as someone mentioned sometime ago), then assuming a branch...

Re: Jumbo 0.5.27

Are you serious ? Really who cares anymore whether Komodo or any other Engine gets updated anymore unless they incorporate MCTC algorithm into it, instead of the now obsolete Alpha-Beta Search. How can we argue against that sterling piece of reasoning :wink: Hope that implementing the Texel method ...

Re: Rare game: SF dev loses in 17 moves with white!

The pgn header has this tag:

[TimeControl "60/60:0/0:0/0"]

I am a bit confused by it. Game ends after 60 moves, with a 60 second time limit?

Re: AlphaZero beats AlphaGo Zero, Stockfish, and Elmo

Y-scale in Fig.2 means Elo without added reference point (that is what that clumsy term google used actually means). It doesn't mean Elo difference between 2 programs, because if it was Elo difference you'd need a single curve, not 2 of them (it's pretty obvious if you just used your head a bit). T...

Re: AlphaZero beats AlphaGo Zero, Stockfish, and Elmo

64 cores to 1 is not like 4096 to 64. Moreover even if it were, the dependency of strength of play vs TTD is also sublinear, and, certainly, is practically bounded. It is actually demonstrated in paper, page 7. Did you read it? Figure 2 is completely bogus. If wish Google actually cited that refere...

From what I can find, Google seems to be calling a motherboard containing 4 ASICs a Cloud TPU, and a TPU pod is 64 Cloud TPUs.

Re: 128-core AMD server

Rates in my area ramp up with usage and I have once in a while hit their "super overcharge now we're really serious" rate level, whatever they actually call it. I am planning to get solar panels on the house next year. --Jon I have a 15 amp breaker that kept tripping. It was hot to the touch. I now...

Re: TCEC 10

Looks like Houdini is good only at these TCs. Rapid and Blitz, its Time Management is HORRIFIC, no matter what value I feed in for Overhead. If you like to analyze chess positions, and you give more than a few seconds of time, then Houdini is a must have. For tactical positions, it simply is the be...
