A weakly universal cellular automaton in the heptagrid (1606.09488v2)
Published 30 Jun 2016 in cs.DM
Abstract: In this paper, we construct a weakly universal cellular automaton in the heptagrid, the tessellation ${7,3}$ which is not rotation invariant but which is truly planar. This result, under these conditions, cannot be improved for the tessellations ${p,3}$.
