Hi there,
I forwarded this to Mike Rudman (Blowfish author) the same day I got it but
i did not get a reply. The Blowfish DLL is adequate but it would still be
nice to have a consistent product that makes the same moves and cube action
as the "real thing" so to speak.
I have 3 (very popular) bots on FIBS mgnu_advanced, mgnu_expert and
mgnu_wclass, using this blowfish dll .it looks bad when they make some
obvious errors( not often.. they are 1900+ but cube action is questionable..
maybe a match equity issue? .. i dont know.. ) that the analyzer calls "very
bad".
So..is it possible to get a dll that has the same behavior as the current
version? A simple "best move/best cube".
These are the only routines that I am currently calling.
EvalInitialise
SetEvalContext
SetCubeInfo
EvaluatePosition
EvaluatePositionCubeful
FindBestMove
I could try to recompile it myself but I get dizzy just looking at the gnubg
code :-) I think I would prefer to leave that to the experts.
best regards..
