PPT-PREDATOR/PREY CELLULAR AUTOMATA

Richard Peters ES 314 Sonoma State University Cellular Automata A cellular automaton is a collection of colored cells on a grid of specified shape that evolves through a number of discrete time steps according to a set of rules based on the states of neighboring cells The rules are then applied iteratively for as many time steps as desired.
