I have exactly the same POVs like you Leo.I dont see a big problem if the "uci only" engines use BookThinker because they usually use a "GUI" book!?Why?Hello,
Fruit would like to participate in the next WBEC-Ridderkerk, but it
would need an opening book!
It will enter as a WinBoard engine, so BookThinker needs to be used.
I don't know anything about BookThinker or making books in general,
so I was just hoping to find somebody here
It can participate without book.
Movei started to play in wbec with no book.
I believe that I do not know more than you about making books.
The book of movei is clearly primitive book that does not know about tranpositions and has only small number of lines that were generated manually.
Movei also does not do an efficient search to find book moves and the time that it needs to find book moves is proportional to the size of the book but fortunately the book is very small so today is not a problem.
I plan to change it but it is not an easy task for me.
I find it unfair if other programmers are going to use bookthinker when I have to work hard only to have an inferior book(I probably need to work some hundreds of hours only to have book that knows about transpositions and is result of the same lines of movei's book including efficient search to find if a position is in book.
I think that only thinker and the commercial programs should be allowed to use bookthinker.
Thinker because the programmer already worked to write the relevant code and
the commercial programs because they have the problem of not being able to use their original book under winboard.
Uri
Ofcourse none of the engines should use the Thinker engine book, not even the commercials, I have made the book for The King myself.
For the uci engines it looks to me as if the authors make a Thinker book thereself or send me a pgn file to make one is fine?
If there are more WB authors that dont like the idee please let me know, here or by email.
Leo.
Best regards,
Günther
