Re: Komodo 14 released.
Couple of questions:
With armageddon enabled, Is it intentional that evaluation should not be going downhill if the outcome will be draw. For example if the game turns out be draw even with armageddon enabled, Komodo may or may not display losing evaluation.
Should i leave contempt at defaut against Houdini 6 or maybe increase it, considering the relative age of ~ 2.5 years since last release.

Re: Komodo 14 released.
If Komodo sees a definite draw when it is set to Must Win, it should show a -20 pawn score. But a drawish endgame will still show a fairly normal score if the draw isn't clear. Default Contempt is optimized for slightly weaker opponent, so it is probably ideal for Houdini 6. Higher Contempt values will score better against engines rated a couple hundred elo below Komodo.Nordlandia wrote: ↑Thu May 14, 2020 1:31 pm Couple of questions:

Re: Komodo 14 released.
We use Ordo for all our testing and estimates, as it corresponds to the way ratings are done in human chess. So our estimated gains should be fairly accurate for CEGT and FastGM, but a bit higher than we would expect CCRL to show on average. Ironically, although BayesElo is not the way human ratings are calculated, when used on engine ratings it is actually a better estimator of human rating differences, because it compensates (partly) for the tendency of engine rating differences to expand. So the choice comes down to whether you want the rating system to correspond to human chess or the actual rating differences!Modern Times wrote: ↑Fri May 15, 2020 12:23 amYes I have +48 Elo so far for MCTS, or +56 Elo if you use Ordo, on the FRC blitz list. Testing still ongoing.

Re: Komodo 14 released.
Testrun for CEGT 5'+3" with Ponder is running, but rather disappointing so far. 400 games only, but -26 to 13.3 is not what I expected...
Let's wait and see

Re: Komodo 14 released.
It is at 1,500 games now on the website. It has lost 5 Elo since the last post, but it still meets your +50 Elo Ordo estimate.lkaufman wrote: ↑Fri May 15, 2020 3:48 amWe use Ordo for all our testing and estimates, as it corresponds to the way ratings are done in human chess.

Re: Komodo 14 released.
The 3375 performance result against Stockfish 11 makes sense, in comparison Komodo 13.3 (3370) only managed a 3320 performance against Stockfish 11. The performance against the weaker opposition such as Boot 6.4 (rated almost 200 elo below K13.3), Ginkgo 2.18 (rated 200 elo below K13.3), and Slowchess Classic 2.1 (rated 226 elo below K13.3) can be due to contempt issues. I imagine once the matches against the top end of the competitors are completed the rating will rise to expected levels.Wolfgang wrote: ↑Fri May 15, 2020 10:41 am Testrun for CEGT 5'+3" with Ponder is running, but rather disappointing so far. 400 games only, but -26 to 13.3 is not what I expected...
