Raffaela 2.1

Postby stegemma » 30 Dec 2013, 18:57

A new more stable version of Raffaela, my chess engine in assembly, is now available for free on my web site:

www.linformatica.com/index-scacchi.php

The software has its own interface but it runs also as a WinBoard engine.

Thanks, Stefano.

Approximately what is the strength of your engine? I am considering to include it in my testing schedule.

Also, does it require some command line parameters to play as a WinBoard engine? I tried it under Arena, its own GUI pops up but it does not make a move under Arena. And what time controls are supported?

Best regards,
Gábor

I think it is about 1600. I've tested on WinBoard but maybe something has to be changed, to work with Arena. I would try it very soon and give you an answer. In olympuschess.com there is a tourney where Raffaela is playing but it seems to make no moves, so maybe the problem is the same. I don't know if they use Arena because i can't contact the web-master of that site.

You don't need any special parameter on command line and Raffaela should accept any time control, with standard WinBoard commands. Maybe try release 2.1.3, not 2.1, to have some bug corrected.

Let me know.

Thanks.

I've found the bug for Raffaela playing on Arena but still there are something strange. The first game now works well but the second one it seems to me that Arena doesn't send the right commands. when first game is engine vs Raffaela, there's no problem. After that, Arena starts the second game with Raffaela playing white and sends those commands:

2014-01-05 19.49.51,515-->1:sd 9999
2014-01-05 19.49.51,525-->1:level 0 2 0

2014-01-05 19.49.51,525-->1:hard
2014-01-05 19.49.51,525-->1:easy

The problem is that WinBoard protocol say that "new" command set engine play black and there are nothing that say Raffaela to start thinking. Maybe I'm missing something in Arena handling of WinBoard protocol?

Unfortunately I am no expert in this. I think the engine should receive the command 'go' to start calculating.

An example of what Arena sends when the other engine has sent its move:

2014-01-05 21:25:39,119-->1:position startpos moves e2e3 g8f6 b2b3 e7e5 c1b2 b8c6 g1f3 e5e4 f3e5 c6e5 b2e5 d7d5 c2c4 d5c4 f1c4 f8d6 e5d6 d8d6 b1c3 e8g8
2014-01-05 21:25:39,119-->1:go wtime 132834 btime 126817 winc 0 binc 0 movestogo 30

Thanks, the other engines run fine in Arena, so the problem should be in Raffaela. Maybe it don't receive all the commands or there are some other problem. I'll solve it then I upload the new release.

After some game, Arena doesn't send the "go" command and suppose that Raffaela is thinking just after the "computer" command. In fact, even the other engine starts thinking just right the "computer" command. this is not the behavior I was expecting but i would try to change this way...

Finally it seems to work!!!

I'm trying some fast Arena tourneys, just to be sure, and then I'll release the new Raffaela engine.

Thanks.

The 2.1.4 release, tested on Arena 3.5, are available on my site:

http://www.linformatica.com/index-scacchi.php

It looses in less than 20 moves against alla the sample engines provided with Arena setup... but it get very interesting mates! :)

Thank you for your efforts, Stefano!

I myself have run a small match against IQ23 which is around 1650 Elo on our list. Here is the PGN, Raffaella managed only one draw out of 10 games. :(

And it is strange that even just before being mated it produces a positive score value for herself. Or e.g. in game 1 it shows +12 for herself (move 10) and one move later it is -10. Then +1.

Best wishes,
Gábor

I myself have run a small match against IQ23 which is around 1650 Elo on our list. Here is the PGN, Raffaella managed only one draw out of 10 games. :(

And it is strange that even just before being mated it produces a positive score value for herself. Or e.g. in game 1 it shows +12 for herself (move 10) and one move later it is -10. Then +1 [...]


The Raffaela score is of the current move (if you take a pawn, it should be +1, for sample) but still it is inaccurate. I've worked this holidays to let it runs fine in Arena, so I haven't debugged the iterative deepening algorithm. I know there's something wrong in my implementation of ID... and i suppose that Raffaela doesn't choose the best move even when she found the right one.

This release is a good starting point to solve the problem, because any bugs in interface seems to be gone.

Thanks for your test, I come back as soon as I have a stronger release.

The release 2.1.5 is a little better:

http://www.linformatica.com/index-scacchi.php

The problem in Raffaela is that it doesn't have quiescent search and the horizon effect has a big impact. No null-moves, no transposition tables... no evaluation function (only piece values and a little of square values).

I'm planning to release Freccia engine, that is more complete and maybe even Satana engine but I need some other week-end of work.
