Re: Leela 43 cores Versus Scorpio 32 cores at TCEC

when leela saturates should it be close to elo of AphaZero? How strong would Alpha Zero be on consumer hardware, though? TPU is roughly equivalent to 10 1080Ti. So A0 would be roughly 40x weaker on 1080Ti, i.e. would have around 1.8knps on average, which considering A0 vs. LC0 network size is a ver...

Re: Slipper next generation: an update

The first 6½ moves are just in the order in which they are generated (assuming you're scanning the board A1, B1...H8, captures first).

But then there's the surprising 7...d6 and all bets are off.

That is ply 59
