The Journal of Cellular Automata publishes high-quality papers where cellular automata are studied theoretically or used as computational models of mathematical, physical, chemical, biological, social and engineering systems.A few examples are given in the list below, which is but a small sample of the areas of interest explored by this journal: Structure formation, heat conduction, self-reproduction, language recognition, evolutionary games, image processing, cryptography, random number generation, computational universality, traffic dynamics, neural networks, alternative discrete-physics models, population dynamics etc.Full length original papers, short communications, reviews and tutorial articles are welcome.
