I'm trying to add in Chispa support for making books from different book formats. My current book entry structure is simple:
{
uint64 hashKey
uint32 gamesWon; // gamesWon are won by white, gamesLost are lost by white
uint32 gamesLost;
uint32 gamesDraw;
}
And now my question: When I import from a RBM book or similar, that don't have info about wins, draws, losses (normal positions, not the marked with "-"), what I must do:
- Add the position as a win
- Add the position as a win, draw and lose simultaneously
- Add the position as a draw
Also I make the same question for Beowulf book format that only have info about games played with each move.
Best regards and Happy new year!

Hi
i asked the same question here but unfortunately i got 0 answers.
I take it as a draw if i don't know the result,but that doesn't seem
to work well so far.I think your idea of taking it as win,draw and lose
simultaneously may be better.or adding another variable to hold unknown
results may help.

I thought about this when I updated the book format of Sharper. I'm not sure I understand your question, but I would add the position with Won/Lost/Draw = 0. That way you know if the position is previously not played (good to know to make sure that the entire book is eventually explored).

I found also in Pepito source code (Pepito can read Beowulf book format) that the moves are added as a win. I don't know exactly why, but my guess is, that the moves are added as a win because are "selected moves". A RBM book have only (or should have) selected moves, guaranteed moves, and that I think it's the reason because should be added as a win.
