Simulation of cell-like self-replication phenomenon in a two-dimensional hybrid cellular automata model

An understanding of the generalized mechanism of self-reproduction is fundamental to applications in various fields, such as the mass-production of molecular machines in nanotechnology. We have developed a model for the simulation of cellular self-reproduction in a two-dimensional cellular automaton, and we have demonstrated that the following three functions can be realized: (1) formation of a border similar to a cell membrane, (2) self-replication while maintaining carrier-containing information, and (3) division of the cell membrane while maintaining the total structure. Furthermore, we have constructed a hybrid cellular automaton model. To reduce the number of transition rules, we considered not only the state transition rules but also the concentration diffusion in the Gray Scott model, in which the self-reproduction phenomenon emerges under certain parameters
