If you meant the latter, 15 ply does not necessarily mean much. Modern chess engines heavily prune and reduce moves that are supposedly bad, so it might be that a sacrifice that seems to be bad at first sight, at a nominal depth/iteration of 15 is actually only searched to a depth of e.g. 5-10. At depth/iteration 30, the move probably is still ...
18 maj 2023 · Recently, a strange engine with a mysterious nickname "Mystery" appeared on CCC, there is no information about it except the most basic one. One of the strangest things is that at 'CCC 20 Rapid: Qualifier #2 (10|3)' it performed poorly. But at the same time, in a one-on-one battle with the "Berserker", it won confidently.

7 lip 2023 · 2. People use Stockfish because: It's free. It's the strongest engine. See CCRL for rating list and the fact that Stockfish has been crushing every other engine in the Top Chess Engine Championship. However: if you're at the level where you don't care about making the best move but rather the move that takes your opponent out of their comfort ...
2 lut 2022 · Run an engine vs engine match, sf14_depth20 vs sf14_5sec. step 1 and 2 compare the total analysis time while step 3 compares the analysis quality. I guess sf14_5sec will win over sf14_depth20, but you have to test this on that hardware.
21 maj 2016 · Then you create a new generation of random piece values through some method of combining values from that best fraction together with small random perturbations. Repeat until the values stabilize. The values you get will probably depend on the specific chess engine (and time controls) you use, but I don't know how strong that effect is.
4 mar 2019 · To figure out which is better, you let the same engine play against itself, with one side using one opening book and the other side the other. If you take care to have each book play white as often as black, you can see in the end which book had a higher score against the other book. For instance, an opening book could contain a line somewhere ...
20 paź 2017 · Presumably, a 2000 rated chess engine should expect a score of about .5 against a human rated 2000. This perhaps makes it easy to verify if chess engines are really approximately the rating they say they are. However, this is problematic for higher rated programs like komodo, who is supposedly around 3250. Obviously, no humans play at this level.
17 sty 2024 · Not long ago, I attended a public lecture by Jon Edwards, the winner of the 2022 World Correspondence Chess Championship. In modern correspondence chess, unlimited engine use is permitted. To get an edge, the top players need to be able to make better use of all the tools available than their competitors can.
17 gru 2014 · For example, depth 8 = 2099 Elo, depth 7 = 2033 Elo, depth 6 = 1966 Elo, and the Elo delta between levels is quite consistently 66 Elo. So extrapolating, depth 5 = 1900, depth 4 = 1834, depth 3 = 1768, depth 2 = 1702, and depth 1 = 1636. Which all seem rather high. Other users have run tests, and the Elo delta actually increases as the search ...
