CELLULAR AUTOMATON Meaning and
Definition
-
A cellular automaton refers to a mathematical model or system that consists of a grid (or lattice) of discrete cells, each of which can exist in one of several possible states. This concept was initially introduced by scientists John von Neumann and Stanislaw Ulam in the 1940s. The cells within the grid can evolve their state over discrete time steps based on a set of predefined rules. These rules determine how the state of a cell is influenced by the states of its neighboring cells.
Cellular automata are often represented in a two-dimensional grid, although they can also be extended to higher dimensions. At each time step, the state of each cell is updated based on the states of its adjacent cells. This update process is typically done simultaneously for all cells in the grid. The new state of a cell is computed by applying the predefined rules to its current state and the states of its neighbors.
Cellular automata have been widely used to explore and simulate complex systems, such as physical processes, biological phenomena, and social behaviors. They have found applications in diverse fields, including physics, biology, computer science, and social sciences. Cellular automata are particularly valuable for modeling systems with simple underlying rules that give rise to complex emergent behavior. They provide a useful framework for studying phenomena like pattern formation, self-organization, and the dynamics of interacting entities.
Etymology of CELLULAR AUTOMATON
The word "cellular automaton" has its roots in Latin and Greek.
The term "cellular" comes from the Latin word "cellula", which means a small room or a cell. It was first used in a biological context to describe the basic unit of life, a cell. In the context of cellular automata, "cellular" refers to the discrete units or cells that the automaton is composed of.
The term "automaton" has its origins in ancient Greek. The Greek word "automatos" means self-moving or self-thinking. In ancient Greece, an automaton was a mechanical device that could perform specific tasks or actions on its own. In the context of cellular automata, "automaton" refers to a mathematical model or simulation that behaves autonomously according to a set of predefined rules.
