Two-Dimensional Block Cellular Automata with a 2×2 Neighborhood
Two-Dimensional Block Cellular Automata with a 2×2 Neighborhood
This is a Demonstration for studying two-dimensional block cellular automata (2D BCA) with 2×2 blocks. You can choose any rule from the rule space and trace the evolution of the system through time. Also, you can show the averages over any one of three axes in 3D spacetime and the density evolution plot. Boundary conditions are periodic. There are three types of tunable initial conditions: random initial conditions with a density and a seed parameter, initial conditions with a 3×3 block on the white background, and latticelike initial conditions with black cells with a certain distance between them on the white background. Also there is a collection of interesting rules in the bookmarks.
