Karl Svozil, Randomness Undecidability in Physics, World Scientific, 1993, [chapters 10.2 - 10.5] also speaks about the simulaton argument. It is not unreasonable - he says - to speculate about the logico-algebraic structure of automaton universes (universes computer generated). If there

Dear Juergen: I certainly currently agree with the idea that a particular universe is a cellular automaton but one that is subject to true noise from an external source. This does not preclude universes that are internally computational rather they are required to balance those that are not
