Frank Walter

[CMCanavessi]

You can just point to the java.exe version that you want.

Thank you Laurens for the quick repair.

Hmm, this one does not move either.

It worked for me in a quick eng vs eng match.

I wonder if it is a java version problem again. I have j8 and j11, maybe the path points to the wrong one.

EDIT: I have just checked and my Arena uses the 8.191 version.

Hmm, that is unfortunate!

FrankWalter should run on both, It is compiled for Java 8, but I tested it on windows with arena with Java 11. Can you maybe post the logging (the logging you see after pressing F4) here, so that I can look into this?

Thanks!

I'm going to look into this tomorrow. Today there are too many matches.

I was using the Shredder GUI, however I just checked using Arena and it still works. So it just may be a Java issue.

Strange. All java engines work all right for me expect FrankWalter. Still does not move. BTW, I thought it was a WinBoard engine, not UCI.

Laurens, here is what I get from Arena upon pressing F4.

Strange. All java engines work all right for me expect FrankWalter. Still does not move. BTW, I thought it was a WinBoard engine, not UCI.

I am using the WB2UCI adapter. Here is my wb2uci.eng config:

Hi Gabor,

It is clear for me what the problem is from the logging: I did not make my program robust enough to guard against unexpected input. FrankWalter expects either a location for the Syzygy tablebases, or no 'egtpath syzygy' command at all.

It fails because it thinks it if fed the Syzygy tablebases location, but the location is the empty string.

I will write some input sanitation code to prevent this issue in the future, and meanwhile I would be much obliged if you could test FrankWalter with Arena with the Syzygy tablebases location (for FrankWalter) configured in Arena.

I really what to thank you all for testing FrankWalter so that I can improve my engine and it's 'user experience'.

Even if I add -tb F:\Sakk\syzygy to the command line it does not move. That is, it moves (very slowly, as if restartig after each move) until it leaves book. After that it does not move at all.
