What are the rules in 1d ?
- pavel_lishin 10mo agoIt only starts out 1-dimensionally, it continues to evolve on a standard GoL grid.
- syncsynchalt 10mo agoThen, importantly, it collapses itself back down to a 1-dimensional copy of its starting representation, but translated.
- boothby 10mo agoSpecifically, after 133_076_755_768 steps, the 1-dimensional pattern reoccurs translated by two pixels. On skimming the thread I haven't determined if that shift is parallel or perpendicular to the line.
- josh11b 10mo agoI think it has to be parallel by symmetry.
- postalrat 10mo agoCan it leave other bits behind after it moves?
- syncsynchalt 10mo agoBy definition of a pure spaceship / glider, no it can't. If it emits persistent "exhaust" that's a "smoking ship"[0]. [0] https://conwaylife.com/wiki/Types_of_spaceships#Smoking_ship https://conwaylife.com/wiki/Types_of_spaceships#Smoking_ship
- quuxplusone 10mo agoIIUC, "smoke" is ephemeral by definition. A spaceship/glider that leaves persistent "debris" in its wake is called a "puffer": https://conwaylife.com/wiki/puffer https://conwaylife.com/wiki/puffer
- HTHThreee 10mo agoSmoke refers to fairly long lived debris that eventually dies out, the term for one that leaves permanent debris is a puffer.
- HTHThreee 10mo agoNo, if it does it's called a puffer.
