Re: Alouette 0.0.1
The version 1956 is buggy. It plays only illegal moves. Sorry for that.

Re: Alouette 0.0.1
No, it works correctly. It was a problem coming from elsewhere. Not sure to have understood what happened, but it looks like Cute Chess doesn't support several engines with the same internal name.Roland Chastain wrote: ↑Mon Apr 29, 2019 10:32 pm The version 1956 is buggy.

Re: Alouette 0.0.1
The above changes were sufficient to reduce stall/disconnect rate in v0.0.3 by a factor of ~10. Good enough for me.tpoppins wrote: ↑Mon Apr 29, 2019 7:05 pm 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 }
but the changes in meilleur.pas are beyond me.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
The few test games played with the latest v0.0.5 showed no problems, certainly nothing severe like illegal moves. I'll report here if I run into any.
Good job, Roland.
I suppose you had problems when running the CLI exec of CC? The GUI won't allow separate engine entries with the same name.

Re: Alouette 0.0.1
Thank you for your message. In fact, the problem came from a modification that I made later (after I posted the zip file). This is what happens when you should go to bed and continue to work.tpoppins wrote: ↑Tue Apr 30, 2019 5:12 pm The few test games played with the latest v0.0.5 showed no problems, certainly nothing severe like illegal moves.

Yes, I use cutechess-cli, but in fact the problem didn't come from Cute Chess.
Thank you for having helped me to find and solve these two bugs.

Alouette 0.0.6 alpha
Hello! A new version of Alouette is coming. Windows binaries are available here. If you are interested in Linux binaries, please let me know it (or else download Free Pascal).
The new Alouette sees four halfmoves ahead (against two halfmoves in the previous version). It recognizes the different forms of the go command and has a time management.
I removed all the little evaluation tricks which were doing nothing. The best move function lies only on the "one recursion" minimax. I just added a bonus for moving pawns first (to avoid repetitions).
I will take some days to make some more tests and polish the code.

Alouette 0.0.6
Hello! Here is Alouette 0.0.6.
Some quick and dirty results, with very short time controls (Cute Chess option "tc=40/40").
Standard variant:
FRC:
If you set "recursion" to 0 in the INI file that Alouette will create, the version 0.0.6 behaves more or less like 0.0.5.
Regards.
Roland

Re: Alouette 0.0.1
Instead of an option in a INI file, I decided to make three different engines, Alouette-A, Alouette-B and... Alouette-C.
Maybe I will come back to the first idea, but for now I find more simple to have several executables. The idea is still to keep the different versions of the program.
Alouette-A searches at depth 1, Alouette-B at depth 2, Alouette-C at depth 4. The three versions use the same positional evaluation: bonus for pawns defending or defended by pawns, bonus for special moves, bonus for threatening opponent's king...
In my tests (tc=40/60), Alouette-B seems stronger.
Standard:
FRC:
I try to improve Alouette-C before doing a release of version 0.0.7.
The weakness of Alouette-C has been explained here.
What do you think of my idea?

Alouette 0.0.7
Hello! Alouette 0.0.7 is available.
Alouette-C (see my previous post) has been repaired and now the hierarchy between the three engines is what I expected.

Re: Alouette 0.0.1
Roland, I downloaded Alouette 0.0.9 and there are 2 binaries inside the zip file, alouette64 and random64. What is random64, a random mover? So kind of the same engine without eval?
