However, this only works for polynomials of degree >=2. Further, the result doesn't hold for linear polynomials (especially any of the form p(x)=x+a, integer a). Moreover, there are problems with the fact that an arbitrary polynomial might not assume the value 1, so it could be the case that neither player wins, especially if the game starts with 1 stone. I think the problem would have to be stated more carefully to explore (4).<BR/><BR/>I agree with the result in (3), but only if we take the convention that 1 is not a power of 2 (contrary to what I am used to).Anonymousnoreply@blogger.com
