Surprise 4.2.3
Posted: 20 Aug 2005, 15:52Hi all,
I have released Surprise-4.2.3 today. Changes against 4.2.3 include:
- Hash key bugfixes concerning ep and castling! (but this did not help much ...)
- Skip some losing captures in qsearch now (still not using SEE)
- Slightly improved move ordering
- Avoid move generation on hash move cutoff now
- Added "pawn to 7th rank" extension at horizon nodes
- Book loading speedup (legality checking of book moves was too slow)
- A couple of internal code improvements
Despite this long list, 4.2.3 is not a major new release, and you should not expect too much. Nevertheless I hope that 4.2.3 is at least a very little bit stronger than 4.2.2.
Have fun with it!
Sven
