Re: Best Nets for Lc0 Page

I have a cheap Radeon RX550 and I am using lc0 v0.26.2 (with Nibbler). With the default net (703810.pb.gz) I get in about 1 minute: 154k nodes (2400N/s) With the J92-145 net I get in 1 minute: 7.7k nodes (120N/s) Which one should I use (assuming the same amount of time will be spent)? Default net ht...

Re: Best Nets for Lc0 Page

Very interesting thread and I understand that with short time controls a small net is necessary as the large one would not have enough time for searching "sufficient" nodes. But how many nodes are sufficient? Is there a minimum number of nodes lc0 should be able to search with any net? If not then t...

Re: "New" Engines (lc0, MCTS, SFNNUE) and suitable GUIs

Any GUI that shows MCTS stats (e.g. Komodo's)? I cannot seem them even in Arena.

"New" Engines (lc0, MCTS, SFNNUE) and suitable GUIs

I am struggling with finding a suitable GUI for the new engines like lc0, KomodoMCTS and StockfishNNUE. Nibbler is great for lc0 but lacks the "usual" features of GUIs like Trees (Aquarium) or Databases (Fritz). On the other hand I cannot get any WDL or other extra info in Aquarium and Fritz. Ideall...

lc0 CPU or GPU if same speed

What would you use, the CPU or the GPU if the speed is (almost) the same?

Chessbase/Fritz Blunder Check and Contempt Settings

I quite like the Blunder Check function in Chessbase/Fritz but I noticed that contempt is handled in a strange way. It seems that contempt is always applied, no matter what the analysis contempt parameter is (even if it is Off). When calculating a score for White then the Contempt value is subtracte...

Lc0 node count and playing strength

With Stockfish or similar CPU engines it is easy to see how "deep" an engine has calculated, either by looking at the search depth or by looking at the total nodes calculated. In practice the search depth is the better indicator as the number is nicer and makes more sense for humans. One could day t...

Re: Leela Output

Stephen makes a very good point.

why not instead show the probability percentage for all three variables based upon the games played
Would that even be possible to display or would be whole structure of the NN need to be changed?

Re: Lc0 Evaluation Explanation

Nice that the most useful explanation came right on my birthday :mrgreen: Yes, useful was meant from a chess point of view. More specifically I am looking for ideas on how to decide between different moves for correspondence chess (CC) but also for an OTB opening repertoire. In CC often times one pr...

Re: Lc0 Evaluation Explanation

Why is Be2 the move that Lc0 selects? It is neither the one with the highest P nor Q nor Q+U nor V value . Do you mean it played Be2 after the screenshot? It looks to me that it does have the highest Q+U, as well as the highest N, but the only one the list of moves is in order for is N (visits). I ...
