Simulation of the Self Organizing Process Using a Stochastic Cellular Automaton |
| |
| Abstract: | As an important instrument in nonlinear scientific research, the cellular automaton provides a useful means for theoretical investigation and computer simulation of complex phenomena. The cellular automaton is here used to study the self organizing processes widely existing in nature. The stochastic mechanism is introduced into the cellular automaton and some models of stochastic cellular automata for self organizing processes of multi particle systems with random movement are developed. The dynamic processes of particle diffusion, sandpile collapse, fractal aggregation, and crystal growth are successfully simulated on PC with the general object oriented Windows program of cellular automata written by the authors. |
