To all,


This is the first "official version" of Horizon:


Horizon’s play after the opening has improved very much. Time management is
finally fixed, so Horizon can now play Blitz or conventional time-control.
(Thanks, Colin!) For downloading, the opening book has now been separated from
the program. The next version will include a file of evaluation parameters for
users to tweak.


2001/11/1 version 1.0
Horrible bug found: Horizon thought it was always playing the opening! That's
why mid-game and endgame play was so mysteriously weak. This bug was introduced
back in version 0.5. Beowulf codebase now supports conventional time-control as
well as Blitz. Beowulf infrastructure problem where hash was always set to 16MB
is now fixed. Changed doubled rooks reward: only given when on semi- or
fully-open files. Found and fixed bug: Rooks on h-file were not recognized
previously. King safety: pumped it up slightly and made uncastled
offense/defense better. Added reward for connected passed pawns.
