XPDNT 061120 released

[David Weller]

Hi all.

I added a 'hashsize entries' command, where size must be (2^n)-1 entries

also, 'ehashsize entries' for evaluation hash - also (2^n)-1 entries

The book is different too. Has most of A00 to E99 with >= 8 half moves.
I know nothing about openings, so this may or may not be optimal

Also, added a SEE.

Here is a Blitz tourney. SOS was losing on time, though.

Im a bit confused, David. I certainly know that bigger isnt always better, but your previous book was over 5000kb in size, and you have changed to a 71kb book. It just seems a little strange.


Best regards,


George

I suppose what im asking is if someone like SSDF was going to test your new version, which book would you prefer he use, the 5000kb book, or the 71kb book?


Regards,


George

Hi George,

The fact is, I just dont know anything about openings, and the only reason I added a book in the first place was for the tournaments.

My choices of 2750.pgn and then 2500.pgn from Dann's site was just a guess that they would be a great place to start.

But then I would see X play lines it obviously didnt understand - and niether did I

So I figured why not just have a smaller, faster loading gook with all the openings represented?

Now I wonder how many of the A00 to E99 are all worth having??

Maybe if I implement some kind of automatic book learning .... ??

Hi all.

...

Where should I type that? On the command line or in an .ini file? I try to compile all open source programs. Unfortunately I can't start your program:

Code: Select all

[volker@E6300 xpdnt]$ ls -l xpdnt
-rwxr-xr-x 1 volker volker 150160 22. Nov 10:55 xpdnt
[volker@E6300 xpdnt]$ ./xpdnt
Cannot open file


IIRC there have to be some files or directories somewhere, but I can't remember.

Hi Volker,

For some reason your post didnt 'show up' as new for me, and it was only when I saw your name, that I thought, 'wait a minute, I dont remember responding to volker?'

Anyway ....

hashsize and ehashsize are like any winboard command - entered in console mode or GUI additional commands or winboard.ini (i think)

There ought to be a /logs subdirectory - sorry for this confusion

Thanks, it works now.
