Alouette 0.0.1

[tpoppins]

I have made a ZIP file including a binary compiled with DEBUG option: it's alouette.exe. The other files (alouette32.exe and alouette64.exe) are binaries compiled with RELEASE option. The main difference is that the DEBUG version produces a log file.

alouette-20190429.zip

@Tirsa
If you have time for a new test, please use alouette.exe.

Thank you for taking the time to look into it, Roland.

Attempting to run alouette.exe produces this error:

Code: Select all

An unhandled exception occurred at $004272D8:
EAssertionFailed: Assertion failed (essais.pas, line 23)
  $004272D8  ESSAIS_$$_init$,  line 39 of essais.pas

and an empty log file.

I tried building from the source you provided in your last post. Same error.

edit: Also built a 64-bit v0.0.3 -- need to test it make our current blitz entry more balanced. It runs without errors but stalls just like the official exec.
Perhaps it's a timing issue. Alouette sends bestmove to the GUI instantly. How about inserting a delay -- say, 100 or 500 ms -- before each command it sends to the GUI?

@Tirsa
Thank you for your message. For the first error that you reported, it's because the program doesn't find the file chess960.fen, which is used for a test (only in the DEBUG version). The file was included in the ZIP file. You can also solve that problem by removing the test unit (named Essais) and recompiling.

Code: Select all

// alouette.pas

program Alouette;

uses
  Classes, SysUtils, Journal, Joueur, Echecs, Outils,
{$ifdef DEBUG}
  //Essais, <----
{$endif}
  Performance;

OK, I will try to add a delay as you suggest. Thank you.

[tpoppins]

Sorry, that was dumb of me to miss the significance of the .fen file. The error went away with the file placed into the same dir.

I ran a short tmt vs. Sapeli RND and set up Cute Chess to abort after the first problem -- Recover crashed engines=off. Concurrency was set to one, to keep things simple. Curiously, this produced the longest uninterrupted series of games I've seen from Alouette so far. It finally stalled on the 21st game after winning 20 in 11 seconds. Log and PGN attached.

[Roland Chastain]

Thank you Tirsa. I can reproduce the bug here. I come back as soon as it is fixed.

[tpoppins]

Good, I'm looking forward to the fix.

While trying to generate some more games for the v0.0.3 entry on the blitz list I managed to unearth this:

If later version didn't explicitly fixed this it's worth looking into, rare as it is.

[Roland Chastain]

OK, the first bug is fixed. It was a very important bug and I wonder how I didn't see it before. Thank you Tirsa.

alouette-201904291647.zip

Now I will make something for the bug that you reported in your latest message.

[tpoppins]

Whoa, that some quick work, Roland!

100 40/2 games vs. Sapeli RND with concurrency=4 completed in 1m 8s without a single error! Bravo!
Now I just need to backport this to v0.0.3 -- since v0.0.5 scores over 90% vs. a random mover v0.0.3 should still be useful.

So far I figured out that the following needs to be inserted in interprete.pas at line 152, after { Promotion }

Code: Select all

    if (Length(ACoup) = 4) and EstUnePromotion(APos, ACoup) then
    begin
      Eteint_(LType^, LDep);
      Allume_(APos.Dames, LDep);
      LType := @APos.Dames;
    end else

but the changes in meilleur.pas are beyond me.

Thank you Tirsa. I believe that the modification above is enough. If I remember correctly, other changes are just extra code that I wrote to find the bug.

But there was a bug in v0.0.3, and I don't remember exactly which one. If you need a version weaker than the current version, I could add a setting for that, to reproduce the behaviour of the previous versions (but without bugs).

[Roland Chastain]

@Tirsa

I fixed the other bug that you have reported (illegal castling).

Thank you very much!
