Re: How powerful is the Queen compared to 2 Rooks ?

I believe that the Alpha Zero team has done a lot of tests with different endgame pieces + pawns configurations. not necessarily thousand of games, but meaningful configurations that helped them to determine a more exact value of each pieces, in which computer has proven different and more exact va...

Re: LC0 bad search and poor tactics

Saying that they do zero tactics of any type (i.e., "don't do tactics period"), however, is perhaps a bit too much hyperbole :D Also nonsense. Looking at positional patterns, there are certain patterns that lend themselves to tactics. This is the whole reason human players practice tactical puzzles...

Re: LC0 bad search and poor tactics

NN don't do tactics period. They recognize patterns only. Search does tactics. If you believe otherwise, delete search entirely, keep training the NN until it plays the right move by only examining the current board position. A ridiculous idea, but it seems you believe in it. This much is wrong. If...

Re: Alphazero news

As a side note, how confident are we that this wide variance with opening type of results for A0/LC0 is due to their learning the game in some very specific way and not due to, say, MCTS' being substantially weaker in certain types of positions? One maybe interesting thing to check would be to see i...

Re: LC0 network 31740 vs Stockfish 10

Except your joke doesn't work, because to even run an OS and chess engines you need a CPU. A GPU alone can't even boot the computer. I can also beat Leela and Stockfish at Tetris and Pacman easily. I'll repeat what I already said to Milos and you quoted: Not my joke, and even if it were, if all jok...

Re: LC0 network 31740 vs Stockfish 10

Your reply as well as the upper attempt of "joke" shows how ppl are actually clueless and lack basic logic (and the wonderful irony in your nickname that is actually name of algorithm that exclusively requires CPU to run). Neither SF nor Lc0 nor any other engine can actually run only on graphics ca...

Re: LCZero Accomplishments and Goals Thus Far

Well, the search algorithm plays the move with the most visits. The initial visit is made to the move with the highest probability from the policy head. With a 1 visit "search", the search will evaluate the position after the move with the highest probability from the policy head, but no matter wha...
