Retrolife and The Pawns Neighbors
Yossi Elran · College Mathematics Journal · 2012
SummaryOne of Martin Gardner's most famous columns introduced John Conway's game of Life. The inverse problem, finding a previous generation in the Game of Life given some extra constraints, was introduced a few years ago and is referred to as Retrolife. In this paper we present a puzzle played on a chessboard that is isomorphic to a variation of Retrolife, in memory of Martin Gardner.
