Undecidability in cellular automata
For 1D cellular automata, almost all questions about ultimate limiting behavior are undecidable, even ones that ask about average properties such as density and entropy.
Pages 818 and 1175 discuss the sequence of all Nand theorems listed in order of increasing complexity.
In all cases the analogs of the picture below have a nested structure.
All are of the so-called parabolic type, so that, unlike my equation, they have no limit on the rate of information propagation, and thus a solution in any region immediately depends on values on the boundary—which in the pictures below is taken to be periodic.
In fact, a fair fraction of all possible transformations based on algebraic functions will yield nested patterns.
The pictures show all the distinct maximal cases that exist for a 7 ×7 grid, corresponding to possible circles with diameters Sqrt[m 2 +n 2 ] .
In practice, such computations are most often done by requiring explicit synchronization of all elements at appropriate points, and implementing this using a mechanism that is outside of the computation.
The reason for this is presumably that all parts of the universe are expanding—with the local consequence that radiation is more often emitted than absorbed, as evidenced by the fact that the night sky is dark.
But in the end, after running programs for a total of several years of computer time—corresponding to more than a million billion logical operations—and creating the equivalent of tens of thousands of pages of pictures, I was finally able to find all of the various examples shown in this chapter and the ones that follow.
And the representations of ≃ 2.718 and all its roots also show definite regularity.
