Could you give us a quick reference for exactly _which_ Euler numbers you're using? Wikipedia has three separate ones and the MathWorld site a similiar number.
Maybe I'm just being stupid. cheers stuart On 26/11/2007, Don Dailey <[EMAIL PROTECTED]> wrote: > > After reading the paper on solving go on small boards, I am curious > about the use of euler numbers as a simple evaluation element. > > I implemented a little euler number test program and it works correctly > from a sample of about 50 positions of various types.
