Decision algorithms for reversibility of one-dimensional non-linear cellular automata under null boundary conditions

Ma Junchi, Chen Weilin, Wang Chen +2

The property of reversibility is quite meaningful for the classic theoretical computer science model, cellular automata. For the reversibility problem for a CA under null boundary…

Efficient Computation for Invertibility Sequence of Banded Toeplitz Matrices

Chen Wang, Chao Wang

When solving systems of banded Toeplitz equations or calculating their inverses, it is necessary to determine the invertibility of the matrices beforehand. In this paper, we equate…

Two Graphs: Resolving the Periodic Reversibility of One-dimensional Finite Cellular Automata

Chen Wang, Junchi Ma, Chao Wang +2

Finite cellular automata (FCA) are widely used in simulating nonlinear complex systems, and their reversibility is closely related to information loss during the evolution. However…

Patterns Induce Injectivity: A New Thinking in Constructing Injective Local Rules of 1D Cellular Automata over

Defu Lin, Weilin Chen, Chen Wang +2

We discovered that certain patterns called injective patterns remain stable during the revolution process, allowing us to create many reversible CA simply by using them to design t…
