If there is some code of another program, than it should be one program with a
similar architecture (e.g. the use of cfg-files etc..)
Similar programs are:
Sachy
Gromit
Beowulf/Horizon
Bestia
Knightx
Lordking
Only Gromit is strong enough that the idea is possible, that some code was
stolen from it. I don't believe so.
The biggest similarities to Ruffian I could reproduce with Crafty 18.15 (In
games aginst each other, the eval is about 99% identical on my computer). But it
as unlikely, that Ruffian is a Crafty clone as it is unlikely to be a Fritz
clone.
Have more trust in the program skills of the author.
