Structural organization in Network Artificial Chemistry by node programs and token flow

Network artificial chemistry (NAC) is revised by introducing man-made node programs and tokens that trigger the execution of the node programs. In place of the former passive and active rewiring rules, all the NAC operations are propelled by mutually dependent operations of the nodes and tokens. From a numerical simulation, it is demonstrated that the revised NAC is able to emulate the organization of a pseudo-lattice structure between hydrophilic nodes, the repulsive relation between hydrophilic and hydrophobic nodes, and the division of hydrophilic cluster.
