For any positive integer parameters a and b, Gurvich recently introduced a generalization mex<Subscript> b </Subscript> of the standard minimum excludant mex=mex<Subscript>1</Subscript>, along with a game NIM(a, b) that extends further Fraenkel’s NIM=NIM(a, 1), which in its turn is a generalization of the classical Wythoff NIM=NIM(1, 1)....</subscript></subscript>
