Re: Google /Alphabet PR
They kind of do - you would expect Stockfish running on 100 CPUs to beat Stockfish running on 1 CPU, which seems to be about the level of disparity here.Unless the computing power is the same you can't say whether Google's algorithm is superior.
Given how amenable chess is (unlike Go) to the brute force style approach I would be surprised if the neural network AI could really produce a better engine.
