A modification of Wythoff Nim

Robbert Fokkink (TU Delft)

Thursday 31st October 16:00-17:00 Maths 311B

Abstract

Wythoff Nim is a two-pile take away game with losing positions that can be coded by the Fibonacci substitution. It turns out that a small modification of the rules of Wythoff Nim produces a take away game that can be coded by the Tribonacci substitution. In this talk I will discuss this modified game and many of the open problems that remain. Joint work with Dan Rust.
