No, I wasn't. Thank you for the link! I'm using a derivative of the drop-out expansion scheme for my book (plus several other forms of expansion). It's standard practice in checkers to use drop-out expansion (DOE) for opening book preparation. Apart from the much smaller branching factor for checke...

Take a look the below paper. IMO it has some limitations and there are some questions for that paper but it may be a good starting point: https://drive.google.com/file/d/0B2pvWWlf39g-NWN0OUpkRE0tem8/view Here is a more recent version of this manuscript: https://drive.google.com/open?id=1FBy-tKExG7C...

Mr. Kaufman, in the chess.com article on AlphaZero, you were quoted as saying "...AlphaZero had effectively built its own opening book...". Could you elaborate on that statement? Did it build its opening book in the sense that it stored moves in a lookup table for opening positions? Or did its train...

Search-Based Opening Book Construction Abstract – An algorithm is described for constructing a chess opening book, to be used in play against an opponent using another book that is given. The book under construction is represented as a Directed Acyclic Graph, with chess positions as nodes and moves ...

Can somebody point me to a reference showing how to convert match scores into ELO differences? E.g. if A and B play a thousand games, and A's win-loss-draw is 250-200-550, what ELO difference between A and B does that indicate?

1. How do you change the tree into a DAG? First of all, one general thing to keep in mind is that space and time efficiency are very much secondary considerations in my data structures and algorithms. My DAG and Priority Queue and Binary Tree manipulations and Given Book lookups are only done in bet...

Search-Based Opening Book Construction Abstract - A procedure is given to construct a chess opening book (OB) to be played against another, given OB. OBs for White and Black are constructed separately. The chess positions of the OB being constructed are represented as nodes in a Directed Acyclic Gr...

Whilst the official Crafty website is unavailable, could somebody point me to a copy of the book.bin and books.bin that comes with version 25.0.1? Thx.

In the xboard I downloaded to Ubuntu Linux, the manpage says -inc disables -mps:

"-inc or -timeIncrement seconds. If this option is specified, `movesPerSession' is ignored. Instead, after each player's move, `timeIncrement' seconds are added to his clock."

I will try -tc 0:10 -inc 0.3

oops I meant "time 30/90/sd/60" (30 moves in 90 minutes then 60 minutes for rest of game)
