Zangdar - petit sorcier deviendra grand

[Carbec]

Hi,

Finally, my little program came to life.
https://github.com/Carbecq/Zangdar

It seems to play honestly. So I am evaluating it against TSCP. I asked some information about , I got this script :

cutechess-cli.exe ^
-srand %RANDOM% ^
-engine cmd=blunder-7.6.0.exe ^
-engine cmd=blunder-7.5.0.exe ^
-openings file=C:%HOMEPATH%\2moves_v2a.pgn format=pgn order=random ^
-each tc=inf/10+0.1 option.Hash=16 proto=uci ^
-games 2 -rounds 2000 -repeat 2 ^
-concurrency 8 ^
-ratinginterval 50 ^
-tournament gauntlet

It uses an opening book. Seems fine, as I noticed that when I do a match, games are sometimes rather identical, so they don't have a big value. But I don't have such a file, how could I have one ?

Thanks

Philippe

Hi Philippe,

I got that specific opening book from here: https://onedrive.live.com/?authkey=%21A ... 05&o=OneUp

Congratulations on getting your engine up and running.

It looks like your engine might play around the level of Blunder 5.0.0, so you might find it helpful as a sparing partner: https://github.com/algerbrex/blunder/re ... tag/v5.0.0

well, i have problems.
I downloaded cute-chess, created a bat file, but it didn't worked. I have this message :

But, If I use the graphical cute-chess, I can do a match.

If anyone have an idea ?

Thanks

I downloaded cute-chess, created a bat file, but it didn't worked. I have this message :

Hello. The protocol for TSCP is xboard.

Code: Select all

-engine name="TSCP" cmd="tscp181.exe" proto="xboard"

[Roland Chastain]

I don't want to tell you what you have to do, but why don't you share the source code?

Linux users (as I am) could try to compile your engine for Linux and test it.

Hi,

About TSCP, i indeed thought that the protocol was perhaps the problem. But modifying the protocol didn't change anything :

Code: Select all

Thanks to Algebrex, I could to a match against Blunder 5. Here are the results :

Code: Select all

Score of Zangdar 0.34 vs Blunder 5.0.0: 34 - 48 - 18  [0.430] 100
...      Zangdar 0.34 playing White: 18 - 23 - 9  [0.450] 50
...      Zangdar 0.34 playing Black: 16 - 25 - 9  [0.410] 50
...      White vs Black: 43 - 39 - 18  [0.520] 100
Elo difference: -49.0 +/- 62.8, LOS: 6.1 %, DrawRatio: 18.0 %

I don't know what to think about the elo, but Im rather satisfied )
Do you know if the games are saved somewhere ? I saw that Zangdar played an illegal move , and I would like to know what happened.

I plan to make public the source. I am now cleaning it. Its just a working program, lots of lines commented out, some parts are just useless. Even for me, its not good. I was too eager to advance ).

Another thing, I begin to be very tired of being disconnected every minute. Sometimes, I can't even (re)logging. How that is it possible ?

Thanks

Hi,

I put the files on Github.

Hi,

I have a strange problem, i got 2 games in a match which ended by "illegal move"; but without saying which move.
How can I progress ? Is there an option that gives more information ?

Thanks

Philippe

To debug I suggest you set the concurrency to 1 (no games played in parallel) and add the "-debug" option. You'll get a very detailed log of what's going on. At least with uci you can just copy and paste the commands that were fed to your engine and reproduce most issues easily.

Also I'd suggest you add the "-pgnout log.pgn" option. Cute chess will then write a PGN for each game that has been played. This can be used together with concurrency > 1 with no problems. All games go into the same log.

Last tip: Consider using faster time controls. I use something like tc=5+0.3 which is a game that starts with 5 seconds on the clock and 300ms increment.

I tried to compile under Linux with this command:

Code: Select all

gcc -o zangdar *.cpp

I get many "undefined reference" errors.
