How to make Edax play faster ?

1) buy a faster computer
2) Use a 64 bits OS. 64 bits Edax version are twice faster than 32-bits
versions.
3) Do not use windows, but Linux. Edax 64-bits under linux is about 20%
faster than edax 64 bits under windows.
4) Enhance Edax code by yourself ;-)
5) Wait for a newer version. Next version will be 4.3 but will not be
really faster.

The only option that may influence edax speed is the size of the
hashtable. You can modify it by using an option on the command line : -h
<n>, -h 24 is usually a good value. The default value is -h 20. It uses
less memory and is not much slower than -h 24.

By default, edax detects the number of CPU and uses them all, so Edax is
already optimal for this.


How to add a book to edax ?

You can build an opening book by yourself using edax with the command
line. If you type help, you will see the following :

Book Commands must be entered in the form 'b|book <command> <parameters>'.
new <n1> <n2> create a new empty book with level <n1> and depth
<n2>.
load [file] load an opening book from a binary opening file.
merge [file] merge an opening book with the current opening book.
save [file] save an opening book to a binary opening file.
import [file] load an opening book from a portable text file.
export [file] save an opening book to a portable text file.
on use the opening book.
off do not use the opening book.
show display details about the current position.
info display book general information.
a|analyze [n] retro-analyze the game using the opening book.
randomness [n] play more various but worse move from the opening
book.
depth [n] change book depth (up to which to add positions).
deepen [n] change book level & reevalute the whole book
(very slow!).
fix fix the opening book: add missing links and
negamax the
whole book tree.
store add the last played game to the opening book.
deviate <n1> <n2> add positions by deviating with a relative error
<n1> and
an absolute error <n2>.
enhance <n1> <n2> add positions by improving score accuracy with a
midgame
error <n1> and an endcut error <n2>.
fill [n] add positions between existing positions.
prune remove unreachable positions.
add [file] add positions from a game base file (txt, ggf, sgf or
wthor format).
