crafty v14.0 is now available on ftp.cis.uab.edu/pub/hyatt
A few notes first:
1. The directory structure on the above machine has changed. The
/pub/hyatt directory contains the read.me and crafty.faq as always.
the /pub/hyatt/common directory contains files common to all of the
versions. directories /pub/hyatt/v11, /pub/hyatt/v12, /pub/hyatt/v13
and /pub/hyatt/v14 contain the sources and executables for the latest
of each of those versions (11, 12 and 13 will eventually be removed
of course.) The files you need for this version are in v14 and
common, unless you already have the book data.
2. Your position.lrn/position.bin files must be removed. They will
cause massive problems with version 14.0, because 14.0 now uses centi-
pawn evaluation resolution, making all the scores in old position.bin
files 10X too large. your old book.lrn can be used, if you want to
hand-edit (or write a program). You must find the end of each book
line that is terminated by {score depth rating-difference} (inside
the {} characters) and take the first value and divide by 10. The
alternative is to take the learn.dat from the v14 directory, which is
my book.lrn file with the 10X correction already repaired. Whichever
you decide to do, you should end up with a new learn.dat (you must
rename your book.lrn to learn.dat if you edit it). You then use the
"import learn.dat clear" to clear old learning stuff and get the
scores from the new learn.dat file.
3. There is no longer a need for the "t" crafty executables, any
executable can now access the tablebase files. To control this, you
use a new command "egtb=n" either on the command line, or in the
crafty.rc/.craftyrc file. n must be 0 (no tablebases supported),
4 (3-4 piece tablebase files only) or 5 (3-4 piece tablebases, plus
KRPKR, KRNKR, KRBKR, KRRKR and KQRKR files *only*). note that no
other tablebase files will be probed unless you modify search.c and
change the test to include them.
Executables will be ready as soon as they are compiled and sent to
me...
