Abstract

− In this paper, we show a construction of a weakly universal cellular automaton in the 3D hyperbolic space with two states. Moreover, based on a new implementation of a railway circuit in the dodecagrid, the construction is a truly 3D-one. This result under the hypothesis of weak universality and in this space cannot be improved.
