Subject: TCB 0043 released

I have just updated my web page:
http://www-leibniz.imag.fr/~coulom/

Here is the description of the new version as documented in tcb.htm:

*  Linux binary released. Note however that it is about 30%
 slower than the Windows version on my P90.
*  Bug corrected : TCB now searches promotions in the
 quiescence search.
* Deep changes in the architecture of the evaluation function.
 Woody Woodpusher, material only and mate only evaluation
 modes are back. The normal evaluation style is very close to
 the previous version, but programmed more efficiently and
 much easier to improve. Improvement of the evaluation
 function will be a priority for next versions. See woody.cui
 for an example of how to set the evaluation mode.
* New command nodelimit in the xboard interface to limit the
 number of nodes searched in a move. This can make TCB
 play more weakly and make a funny opponent for a weak
 human player, especially if combined with the Woody
 Woodpusher evaluation style. Do not forget to disable
 pondering when using this command so that TCB does not
 take a lot of time to think when it predicts your move
 correctly.
* Hash table algorithm changed. There is now only one table,
 the size of which is given in bytes. Do not forget to update
 your initialization files : size 20 will give a hash table with a
 single entry, not 1 million as before.
* xboard new command does not clear the hash table any more.
 This should improve the playing strength when TCB is used
 in the Fritz interface. A new command, clearmem has been
 added in the engine interface so that it can be cleared
 manually.
* A few moves added to the opening book
* Node count is now displayed

Enjoy,

Remi
