Abstract

Since Conway proposed the Game of Life, it has attracted researchers' attention due to complex "life" evolutions despite simple rules. It is known that the Game of Life exhibits self-organized criticality, which might be related to scale-free evolutions. Despite the interesting phenomenon of self-organized criticality, the Game of Life turns to steady states within several generations. Here, we demonstrate a new version of the Game of Life in which cells tried to stay "alive" even though neighboring sites were over- or underpopulated. These rule changings enabled the system to show scale-free evolutions for many generations.
