Cellular automata complexity trade-offs*
TLDR
It is demonstrated that any linear time cost can be eliminated and, in fact, a speed-up by arbitrary positive integer factor k can be attained at an increased structural cost.Abstract:
The general theory of cellular automata is investigated with special attention to structural complexity. In particular, simulation of cellular automata by cellular automata is used to make explicit trade-off relationships between neighborhood size and state-set cardinality. A minimum neighborhood template with d + 1 elements is established for the class of d -dimensional cellular automata. The minimum state set for this class is shown to be the binary state set. The temporal costs, if any, of structural complexity trade-offs are also studied. It is demonstrated that any linear time cost can be eliminated and, in fact, a speed-up by arbitrary positive integer factor k can be attained at an increased structural cost.read more

Real-time language recognition by one-dimensional cellular automata
TL;DR: Pattern recognition by parallel devices is investigated by studying the formal language recognition capabilities of one-dimensional cellular automata, finding that nondeterministic bounded cellular Automata can recognize the context-free languages in real time.

Real-Time Computation by n-Dimensional Iterative Arrays of Finite-State Machines
TL;DR: An n-dimensional iterative array of finite-state machines is formally introduced as a real-time tape acceptor and the computational characteristics of iterative arrays are illuminated by establishing several results concerning the sets of tapes that they recognize.
