摘要

We investigate number conservation in non-uniform one-dimensional binary cellular automata with a neighborhood of size four. In this setting, cells may follow distinct local rules, leading to a wide range of dynamic behaviors. It is known that one way to synthesize such cellular automata on a finite grid of a given length is to use concatenation of smaller blocks, which are themselves number-conserving. By introducing new mathematical tools, we were able to find and describe in detail the dynamics of all such blocks of length less than five.
