Lights Out!: A Survey of Parity Domination in Grid Graphs
... is key to understanding the complete solvability of grid graphs. Problem 1 Let p(x) be factor of one of {f2k +1 (x), f2k −1 (x)}, say it is a factor of f2k +1 (x). Can one characterize when is p(x+1) a factor of f2k +1 (x) and when is it a factor of f2k −1 (x)? A more concrete question about grid gr ...
