Cellular automata, often described as "simple machines with complex behavior," are a fascinating area of study in electrical engineering. These systems, comprised of a large number of identical, interconnected cells, operate by repeatedly applying a set of simple rules to each cell. Despite their basic nature, cellular automata are capable of producing remarkably intricate and dynamic patterns, making them a powerful tool for tackling complex problems in various fields.
Understanding the Basics:
Imagine a grid of cells, each with a finite number of possible states, like "on" and "off" or "black" and "white." Each cell interacts only with its immediate neighbors, following predetermined rules that dictate how its state evolves based on the states of its neighbors. These rules are applied synchronously to all cells at fixed intervals, leading to a cascading effect that creates intricate patterns and behaviors.
