When are translations of P-positions of Wythoff's game P-positions?
Aviezri S. Fraenkel, Nhan Bao Ho
We study the problem whether there exist variants of {\sc Wythoff}'s game whose -positions, except for a finite number, are obtained from those of {\sc Wythoff}'s game by adding…
Variants of Wythoff's game translating its P-positions
Nhan Bao Ho
We introduce a restriction of Wythoff's game, which we call F-Wythoff, in which the integer ratio of entries must not change if an equal number of tokens are removed from both pile…
Two variants of Wythoff's game preserving its P-positions
Nhan Bao Ho
We present two variants of Wythoff's game. The first game is a restriction of Wythoff's game in which removing tokens from the smaller pile is not allowed if the two entries are no…
A restriction of Euclid
Grant Cairns, Nhan Bao Ho
Euclid is a well known two-player impartial combinatorial game. A position in Euclid is a pair of positive integers and the players move alternately by subtracting a positive integ…
