Chemical Organization Theory as a Theoretical Base for Chemical Computing

In chemical computing, a theoretical analysis to cope with the emergent behavior is required. In this paper, we exemplified with xor logic gate and flip-flop circuit how chemical organization theory can help in designing and understanding chemical computing systems. The reaction network implementing the boolean computation is decomposed into a hierarchical self-maintaining sub-network (organization), and the dynamical behavior is explained as a movement between the organizations. The theoretical analysis provides an insight into potential emergent behaviors. The results are encouraging so that the theory of chemical organization contributes to a theoretical base for emergent computing.
