Re: When will the chess programmers write an engine that plans ?

Total playouts. Thats actually full games, so a "node" means something completely different from SF's nodes. You're comparing apples to oranges here. This is simply wrong. Leela does not perform playouts of the whole game in its search. A playout means navigating from the root via the PUCT algorith...

Re: When will the chess programmers write an engine that plans ?

Another important thing to keep in mind is that humans do quite a lot of computations themselves; it's just that we're consciously aware of very few of them. With engines, we're aware of all that they have to do to play high-level chess, which can make it seem like a more drastic difference than it ...

Re: When will the chess programmers write an engine that plans ?

To be honest all that has changed from the origins of chess until today is the hardware. :?: So, no software improvements at all? On equal hardware, I should expect Fritz 10 to hold its own with SF 11, or, sticking with the same engine across time, SF 5 to hold its own with SF 11? It's almost as if...

Re: The Stockfish of shogi

On qhapaq's site the listed ELO for dolphin1/orqha1018 is 4393. AlphaZero[1] Shogi's ELO is apparently around 4400, and DeepMind's MuZero[2] apparently has a shogi ELO of about 4700. I had to eyeball those last two since I can't see an explict ELO figure given - presumably I'm overlooking something...

Re: Turning off 50-move draw rule in Stockfish & other engines

If we're just wanting to test the idea, it seems it might be simpler to find a difficult TB position where the conversion is ,say, 30 moves away (or some such depth), and see if SF finds the win faster with 50-move ply counter set to 0 than with it at 39, instead of trying to make absolutely sure th...

Re: 1.g4 opening is losing?

That output is expected score in hundredths of a percent, so it thinks white's best is an expected score of just under 26%

Re: mmt Vs. Ovyron (G4 D5 BG2)

As a minor note, it seems the move order in the game updates got changed somewhere along the way (too lazy to track down exactly where).

Game started 1.g4 d5 2.Bg2, but game updates are showing 1.g4 d5 2.c4 as the beginning.

Re: Lomonosov - what is the mate-distance...

It's not that the syzygy tables are "wrong" simpliciter or unreliable.

They're DTZ, not DTM, and DTZ-optimal play will very often not be DTM-optimal.

Since the OP wanted to know shortest forced mate, offering a DTZ-optimal solution from syzygy didn't help him much :)

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...
