Historic Milestone: AlphaZero

[gladius]

Simply incredible. The end of traditional human coded heuristics is upon us!

What a tremendous achievement, since alpha-beta was introduced more than 50 years ago, it's been *the* way to search in chess. MCTS wasn't even on the radar! A huge shift in the landscape.

ALphaZero did win Stockfish in 100 game scored 64/100 that is 98 elo stronger than Stockfish TCEC 2016. Not bad ! I d like to see it more trained to see how far from perfect Stockfish really is !

First example game, Stockfish-Alphazero 0-1

To say that i'm impressed is a understatement. Shocking.
Take note that SF was at 64 cores!

Not so fast folks...And just what were the exact parameters of the test?
What opening book....? ..time control was 1 minute per move!!..
...more testing needed..A Lot More Testing.....Lets Wait and See.....Hopefully This time they won't dismantle the chess program/engine!!...AR
