Java Cells: Exploring the World of Cellular Automata

Cellular automata are fascinating mathematical models that have been extensively studied in various fields such as computer science, physics, and biology. In this article, we will delve into the world of cellular automata using Java, a popular programming language known for its versatility and robustness.

What are Cellular Automata?

Cellular automata are discrete models that consist of a grid of cells, each of which can be in one of several states. The state of a cell is determined by a set of rules that define how it changes based on the states of its neighboring cells. These rules are applied simultaneously to all cells in each generation, leading to emergent patterns and behaviors.

Implementing a Simple Cellular Automaton in Java

Let's create a simple 1-dimensional cellular automaton in Java. In this example, each cell can be in one of two states, 0 or 1. The state of each cell in the next generation is determined by the states of its two neighbors in the current generation. We will use the concept of periodic boundary conditions, where the first and last cells are considered neighbors.

public class CellularAutomaton {
    public static void main(String[] args) {
        int[] cells = {0, 1, 0, 1, 1, 0, 1, 0};

        int[] nextGeneration = new int[cells.length];
        
        for (int i = 0; i < cells.length; i++) {
            int left = cells[(i - 1 + cells.length) % cells.length];
            int right = cells[(i + 1) % cells.length];
            
            nextGeneration[i] = (left + cells[i] + right) % 2;
        }
        
        for (int cell : nextGeneration) {
            System.out.print(cell + " ");
        }
    }
}
