Nature-inspired computations using an evolving multi-set of agents

A multiset of agents can mimic the evolution of the nature-inspired computations, e.g., genetic, self-organized criticality and active walker (swarm and ant intelligence) models. Since the reaction rules are inherently parallel, any number of actions can be performed cooperatively or competitively among the subsets of,the agents, so that the system evolve reaches an equilibrium, a chaotic or a self.-organized emergent state. Examples of natural evolution, including wasp nest:,construction through a probabilistic shape-grammar are provided
