Hi Ed,
Thank you very much for the wonderful news.

Hi Michel,
I'm wondering about this question. Why did you never think about using better compression to reduce the database size?

Krzysztof

Thanks for the reply Ed. Can you tell me how much space a 10 figure database would take in GB? Of course, in draughts 10x10.

I have not worked out the details for 10 pieces. Building that requires more computing hardware than is available to the typical draughts programmer. AFAIK no one has ...

Krzysztof, in my tests kingsrow performed the same with either db in engine matches, and in test positions of 12 to 16 pieces measuring search time to obtain an egdb win or loss score. However version 1 is 389 GB vs 56 GB for version 2, so version 2 is much easier to manage on your internal drive ...

Ed,
I have a question. As you wrote, you have 2 versions of the databases. Which one is better and more accurate.

Hi Michel,
I present a problem with generating databases. Program version 5.0. After starting the program, I select options , then Endgame and Create endgame databases .I have this window - I select the options marked in red . Applies to 5v2 and 4v3 bases. And nothing happens for several days ...

Hi Michel,
I've been waiting for 3 days and nothing is happening. Can you fix this or do something about it. Applies to program version 5.0. Screenshot from version 4.8.0 but the same thing happens.



Krzysztof

Thank you for your answer Harm.

Krzysztof, for DAM 2.2 you just need to have a PDN file with the set of games that represent the ballot openings. With DAM 2.2 you can open that file and select the desired game as opening position, and then start manual play from there.


But does this only apply to Dam 2.2 or does it also apply ...

Thank you for the new version of the program.

Dragon can, but you need to put a pdn file with the positions in the dxp directory. I forgot to add that to the installer.

I will fix in the next update, working on that.

You will also be able to run damexchange directly from the engine, for any list of pdn files. No GUI overhead. Just start the ...

After this you can start the game as usual.

Thank you, Frank.

Bert, yes.

Bert, thanks for your reply. These are the normal versions. There is no need to use dxp or hub. I'm more interested in playing between two computers in a tournament.

I have a question. Can the following programs below play 3-move ballot openings?
