This article is a stub. You can help LifeWiki by expanding it. This article needs to be expanded with: how rewinding a pattern is conceptually same as/different from searching for a (more or less arbitrary) predecessor of the pattern, and in practice how to rewind/find predecessor for arbitrary (including periodic and non-periodic) patterns, with or without context of glider synthesis |
To rewind a pattern is to change it into a form that it would have looked several generations earlier.[1]
For glider syntheses or other multi-object collisions, rewinding the pattern amounts to moving every spaceship and every oscillator back in time by the same number of ticks. A synthesis is only considered valid when it can be rewound back by an arbitrary number of generations.[2]
There is a python script that rewinds standard spaceships, blinkers and beacons in a given pattern by one tick.[3]
