Hello.
I may have found the answer to the problem with SOS playing weak as compared to the earliest version as was discussed earlier. I had noticed that it was playing weak as well on my machine (win98 AMD266) using the file CYGWin1.dll (dated 1/4/99). I copied an older version from my Gromit directory cygwinb19.dll (dated 12/3/98) and renamed it to cygwin1.dll. SOS seems to be winning many more games now on my machine
Hope this may be of help,
Andrew Tanner
Correction to the above post. cygwin1.dll (dated 12/3/98) *originally* came from the directory of the chess program PIERRE. I then renamed it to cygwinb19.dll so that it could work under Gromit. The file cygwinb19.dll should *not* be renamed and used for SOS. At the present time I do not know why the older version of cygwin1.dll (dated 12/3/98) enables SOS to play stronger on my machine.
Frank Schneider reports in Gromit's documentation that:
The cygwinb19.dll has a broken memorymanagement which sometimes causes
problems with the allocation of hashtables.
Compiling the source using the B20 compiler failed, because when optimizing,
it generated an engine.exe that produced wrong results. Therefore B19 is
used to compile the source and the B20-dll (cygwin1.dll) should be used
to run it
