Building book.bin is a simple exercise and requires +nothing other than the raw input file you are going to use. +Generally this will be either medium.zip or the set of four +files large[1-4].zip, all of which are stored on the ftp +machine ftp.cis.uab.edu/pub/hyatt/. + +To create the file book.bin, you need a PGN game collection +that is a *real* PGN-compliant file. Supposing this file is +called "large.pgn" you would use the following command: + +book create large.pgn [n] [wpct] + +The only thing you have to supply is , a number indicat- +ing how many moves from each game are to be stored in the +book.bin database. I typically use 60, which stores the +first 60 moves from each game. Increasing this number +slightly increases the probability that Crafty will stay in +book longer, but it also increases the probability that it +will follow a game too far, so that it begins to reach posi- +tions where the move actually played might not be the best +move, letting it fall into a bad hole. Increasing this also +increases the size of the database as well. + +You can decrease the size of the book, and also reduce the +number of ugly moves by specifying , which says that +unless a move is played in at least N games, the move is +discarded. This will substantially decrease the size of the +book.bin file, and also eliminate single game moves that +often have significant errors or blunders. + +You can increase the quality of book lines by specifying + which is the "winning percentage". This is specified +as a percentage of lost games, and is used to discard moves +that led to mostly losses. A safe value is 50, which says +that if a particular opening move didn't win at least 50% as +many games as it lost, the move is culled. A value of 100 +would mean that moves are culled if they produced more +losses than wins, and is really a strict criterion. + +After creating book.bin, you need to create books.bin. This +is a small version of book.bin, which is intended to give +you more control over the moves/openings Crafty will play. +This is usually built from the file start.pgn on the ftp +machine, but you can modify this file to suit your taste +easily. To build books.bin, you use the following command: + +books create start.pgn 60 + +Again, 60 is what I use, but none of my start.pgn lines go +anywhere near that many moves. The main point here is that +in start.pgn, you can append a "!" to any move you want, and +when it is Crafty's turn to move for that color, it will +play from the set of moves with "!" if there are any, ignor- +ing the rest of the book moves. If you only want it to play +1. e4 as white, you would just enter the short game: + +[Crafty only plays 1. e4] 1. e4! + +and you are finished!. You can enter as many as you want. +If on the other hand there is a move you don't want Crafty +to play, then follow that move with a "?" and it will never +play it. Moves in books.bin that are not flagged with ! or +? don't have any influence on Crafty's choice at all. + +Here's how the files are used. When searching a position, +Crafty first enumerates the set of moves it can find in the +opening database. It then does the same for the books.bin +database, and performs a "merge" operation to combine the ? +and ! flags... The purpose of the books.bin file is to give +you a small database that you can easily modify, rebuild, +and repeat this process over and over. Since it takes a +fraction of a second to completely rebuild this file, it is +very easy to modify this to control what Crafty will play, +without having to rebuild the large database. + +One important characteristic of the PGN input is the Result +tag must be specified in most of the lines, because Crafty +counts wins, losses and draws for each book move and uses +these counts with some of the book selection options given +below. + +How the flags are used. + +The ! and ? flags should only appear in the small books.bin +file, although there is no reason why they can not appear in +the large file as well. For this discussion, it doesn't +matter since Crafty takes the moves from both files and +"merges" the flags/etc into one entry for each move. + +Quite simply, if any book legal book move has a ! flag, then +Crafty will only play moves from the set of moves which all +have the ! flag. If a move has a ? flag, then that move is +immediately removed from the set of possible book moves. If +the only legal book move has a ? flag, it will not be played +as a book move and Crafty will simply pretend that it found +no book moves and will execute a normal tree search. Pretty +simple. + +How to control the frequency of opening move selection. + +A new feature in version 15.15 and beyond allows you to +append a PGN comment to any move in a text file used to cre- +ate books.bin, of the form {play nn%}. This will force the +move it follows to be played that percentage of the time, +regardless of the normal book-ordering values based on fre- +quency and so forth. + +Note that {play 0%} will not prevent a move from being +played at all, as this will look just like a move with no +percent specified. To avoid playing a move, use the ? flag. + +How does Crafty choose book moves? + +Crafty's book selection algorithm depends on two user- +defined values that can be set at any time during a game: + +book random + +book width + +The selection algorithm first finds the set of legal book +moves as above. This set will either be all ! moves, or +will have no ! moves in it. This set is then sorted based +on the setting of book random. Here's the options: + +book random 0. This is a special case for book selection. +Crafty simply takes the set of book moves, and searches only +these moves using a normal alpha/beta search, but with a +shorter than usual time limit. It then plays the move that +produces the best search value. This has one serious disad- +vantage in that there is no randomness to this at all. It +will always play the same move in the same position, unless +the evaluation is modified, or the time per move is differ- +ent enough to let the search find a different move from the +book move set. + +book random 1. This enables a random form of book move +selection, but you have a lot of control over how moves are +randomly chosen. The moves are ordered, based on 4 +parameters: frequency of play, win/lose ratio, static eval- +uation and learned results. Normally these are factored +into the value used to sort the moves, based on default set- +tings that you can modify by using the command "bookw option +N" "option" should be "freq", "ratio", "eval", "learn", or +"CAP". N should be any real number between 0 and 1. + +Crafty finds the min and max values for each of the 4 param- +eters, and then maps this into the range 0-1000 for each +parameter. Each parameter is multiplied by the correspond- +ing "weight" you have assigned, and this is used as a value +to sort the moves from low to high. Note that the first +sort value is always the "play percent" to move them to the +top of the list. For moves with equal "play percent" val- +ues, the normal sort-value is used as the second-level sort +variable (if no moves have a play-percent, then this second- +level variable is the only one used, of course.) + +Once Crafty has sorted the moves as given above, it next +excludes any book moves which have 0 wins. This culls the +odd lines where a player chose a bad line and lost quickly. +With zero wins, it will never be chosen, although Crafty +will happily follow it from the other side. :) This is not +anywhere near perfect, however, because an opening could +have 1 win and 19 losses and that still would stay in the +list. + +If a move has a learned value of > 100, this move is ele- +vated in priority to that of a ! move, since it appears to +win material instantly. If a value is < -100, it is given a +? since it appears to be a lemon. + +After this, the setting for "book width " is used to keep +the first moves in the list, after the above culling has +been completed. The smaller you make the less random- +ness you get, but the chance of Crafty popping out a really +bizarre book move gets smaller as well. + +After sorting, the final step is to fold in any mandatory +"play percent" values. What this step does is that it finds +all the moves in the "playable move set" just computed, +which have no percent-to-play value set. It sums the sort- +values for these moves, then adjusts the sort-values for the +other moves so that their percentages will be honored. + +Once this has been done, crafty simply uses the "sort value" +for each move to compute a total for all moves. It then +generates a random number between 1 and this limit, and +chooses the move that this probability distribution matches. +This will certainly evolve over time as new ideas are devel- +oped. + +For my play on ICC, I use book random 1, and book width 5 +normally, although for titled players this is reduced to +book width 3. For computers, I reduce this further to 2, to +try to play reasonable openings and cull the gambits and +things that don't work out. + +How does book learning work and how can I share learned +results? + +1. *all* of crafty's "learned knowledge" is in the book.bin +file. It keeps the learned value and learned count right in +the book file for speed. You can't modify it, although +"show book" will make crafty display all the book stuff +before it makes a move. + +2. the book.lrn file has two purposes: (a) to serve as a +log for your prying eyes, so you can see what it's learned, +against whom, and what the score was that got its attention +in the first place. The values on the end of each book +line, inside the {} characters are as follows: + {value, depth, rating_difference} value is the value of +the "key" search that comes from the first 10 moves out of +book. it's in centipawns, and + is good - is bad. depth is +the depth the search reached at this "key" position, the +deeper the search, the more the value is "trusted." rat- +ing_difference is crafty's rating - opponent's rating a neg- +ative value means pay more attention to the score since the +opponent is better than crafty, a positive value means to +take the score with a grain of salt, because the opponent +was weaker than Crafty. + +You can delete this file at any time, and it has no effect +on learning. As I mentioned, the learning takes place in +book.bin... this is mainly for you to peek at if you are +interested. However, this is the "portable learning data +file" also, and can be given to others to import into their +crafty, where it will affect the opening book just like +their crafty had played the openings and got the same +scores. There are two ways to use such "lrn" files: + +1. "import " will read and import the +knowledge therein into your book.bin. Since I use the same +learning code as is used when playing games, this informa- +tion also gets appended to *your* book.lrn file as well, so +that your book.lrn always reflects *everything* your program +has learned, so long as you don't ever remove this file. It +would be a mistake to use this command on your own book.lrn +file, because the things would get counted twice, which +might or might not be a good thing. + +2. "import clear" will read is no longer around) which will +import either book.lrn type data or position.lrn type data +and can tell them apart without your having to do anything. +The option is still there, should you want to use +it, and simply removes the position.lrn and position.bin +files before starting the import process for position learn- +ing. + +This can be turned off, if you like, by checking out the +"learn" command, which gives you the ability to turn off +book learning (as it presently works), position learning, +and the next book learning stage which will add to the book +in addition to learning which book lines are good and bad. + +What is this new "result" learning? + +Result learning works just like normal book learning, except +that if Crafty is checkmated or resigns, it will step back +through the book line to find the last point where it had +more than one move to choose from. It will flag the move it +chose as "never play again". + +This handles the case where the first ten non-book moves +produce reasonable scores, but the position is one that +Crafty simply can't handle very well. If it loses such a +game, it will still vary the next time this opening is +played, as otherwise it would possibly repeat the same open- +ing, and would certainly repeat the remainder of the game. + +All three learning modes are turned on by default, although +any of them can be disabled with the appropriate command +option to "learn". +
