How exactly do you know, you have a good storage size?
I got
nused 97975
0: 2025
etc etc. Most efficent size occurs when "nused" is as close to zero as >>>possible or is
This looks fine. If the 0: line is between about 1 and 30%, everything
is ok.
1% to 30% of what figure?
I've also being thinking about the use of ! or ? for marking Yace
opening books.
Do you have to mark the PGN files with such comments then complie it?
That would be quite troublesome for big books..
The number, you have given as the initial size. After rethinking,
I assume, that a good value for the initial size should be the
number shown as nused. No experience with large books though.
I assume the numbers you have posted here are not about the
large book from the other message. nused is the number of different
book positions, it would seem much too low for such a large book.
How long did the creation of the large book take?
Also, please note, that all public available versions of Yace have
a bug in the book move selection code, when the sum of counts for the
different moves (Yace shows them in the log) is very high. Then, it
will just not consider moves further down in the list. I think, there
should be no problem with the book created from 2600.pgn, but I
suspect, that with your large book, you will see it. If you like,
I can mail you a fixed version.
I first thought about a scheme, like the one I suggested to you
for adding book lines. Just copy the original PGN file and your
marked lines together and create a new book.
It might however be more convenient for users, to have a crafty like
books.bin. I will think about it.
Book learning will need some time ...
