[JJJ]

In ippon rating list, Houdini barely below Stockfish 8. Too close to say for now.

Has anyone tried any chess960 games ?

Additionally, didnt Houdart say that his dev version is about 30 elo stronger ?

Good luck in the Superfinal Houdart with Houdini. Houdini 5 looks really impressive; I did not think that Houdini would beat Komodo so handily in the IPON tests. It should be a great 100 games in the Superfinal to watch. Best of luck.

As we've discussed via e-mail, there is an issue in some GUIs with Houdini 5 not correctly reading the Chess960 castling codes.

I will publish an updated Houdini 5.01 in a couple of days that will correct this, together with some other corrections.
Thank you for your patience with a rusty developer .

Ingo, thank you for running the test.
+179 Elo in the TOP 16 list is decently close to the 200 marketing Elo, I guess I can keep the value .

What about the Android version? How long we must wait for Houdroid, the thing that never came...? Come on, seriously

It's coming for sure, what's another month after 3 years?

Will there be an Ipad version?

Thanks.

Thank you for your patience with a rusty developer :).

Robert, while you're prepping the 5.01 update, may I ask you for a small feature that would take five minutes to code and should make a lot of ppl using Houdini for analysis happy? I mean a UCI option to hide fail-highs/lows.

In Stockfish it takes just two extra lines of code (marked with "+" below):

search.cpp:

Code: Select all

              // When failing high/low give some update (without cluttering
              // the UI) before a re-search.
              if (   mainThread
                  && multiPV == 1
                  && (bestValue <= alpha || bestValue >= beta)
                  && Time.elapsed() > 3000
+                 && Options["Show Fail High and Fail Low"])
                  sync_cout << UCI::pv(rootPos, rootDepth, alpha, beta) << sync_endl;

ucioption.cpp

Code: Select all

   o["SyzygyProbeDepth"]      << Option(1, 1, 100);
   o["Syzygy50MoveRule"]      << Option(true);
   o["SyzygyProbeLimit"]      << Option(6, 0, 6);
+  o["Show Fail High and Fail Low"] << Option(false);
