Cellular automaton to map one vector to another in a special way [closed]

I have 2 vectors: Vector J of dimensionality N Vector K of dimensionality M M >> N by order(s) of magnitude. I need to find a cellular automaton G: K -> G -> J G however needs to be such that ...

Setting initial conditions of a domain grid?

So I'm writing some code to try and produce a cellular automaton which will model an oscillatory chemical reaction, but I'm trying to set up the initial conditions of the grid so that I can vary them ...

How to create a cylinder with where the walls represent the output of a cellular automaton [duplicate]

So i'm trying to do this implementation of cellular automaton which replicates some random patterns generated by 3D printers like the ones below. I'd basically like to create a model which looks ...

Issues reproducing reversible CA from NKS

I want to recreate the output of the reversible cellular automaton described in this page of the NKS book. The book specifies that this is a modified version of R214, where the new state (step+1) ...

Using ParallelMap to run multiple Game of Life simulations simultaniously

My Assignment and Code As an exercise in Parallel computing I've been tasked with implementing Conway's GoL in a way such that at every iteration only a fraction of cells are updated. I'm then to run ...

Cellular Automata Neighborhood as Node connections

Can I use the CellularAutomation[] function where the neighborhood is defined by the connections between nodes? For example, if 1 -> 2, 1 -> 3, 1 -> 8, 1 ->1, then the neighborhood of node 1 is the ...
