We introduce a new model of cellular automaton called a one-dimensional number-conserving partitioned cellular automaton (NC-PCA). An NC-PCA is a system such that a state of a cell is represented by a triple of non-negative integers, and the total (i.e., sum) of integers over the configuration is conserved throughout its evolving (computing) process. It can be thought as a kind of modelization of the physical conservation law of mass (particles) or energy. We also define a reversible...

We want to discuss some properties of one-dimensional, radius 1, CUCAs (we denote by CUCA a Computationally Universal Cellular Automaton; see later on for the definitions). In particular, on one hand we want to keep small the number of states (the first example of «small» CUCA is due to Smith III [13]; it requires 18 states); on the other hand we are interested into automata, possibly requiring a high number of states, whose transition law is «as simple as possible»; e.g. totalistic...
