Title: Persistence of Complex Patterns in Lenia and Their Physical Interpretation
Abstract: Lenia is a two-dimensional continuous cellular automaton conceived as an extension of the Game of Life. It generates localized, moving patterns with diverse and complex shapes that persist over time. This life-like behavior appears qualitatively different from patterns observed in physical systems such as reaction-diffusion (RD) systems, although some patterns in Lenia resemble those in RD systems. Motivated by this observation, we explore how Lenia differs from physical systems by examining the underlying dynamics. By identifying similarities and differences, we aim to understand how Lenia's specific features lead to the maintenance of complex patterns, which we regard as its form of goal-directed behavior.
