One round trip from the whole to its parts and back is probably not enough to generate complex self-organizing systems with emergent phenomena. If the two-way method of “synthetic microanalysis” works at all, you will certainly need some iterations and a number of stepwise refinements until the method converges to a suitable solution. | One round trip from the whole to its parts and back is probably not enough to generate complex self-organizing systems with emergent phenomena.

It is important to identify and refine before each iteration suitable subsystems, basic compounds and essential phenomena on the macroscopic level, which are big and frequent enough to be typical or characteristic of the system, but small and regular enough to be explained well by a set of microscopic processes. Many macroscopic descriptions are only an approximation, idealization and simplification of real processes. | It is important to identify and refine before each iteration suitable subsystems, basic compounds and essential phenomena on the macroscopic level, which are big and frequent enough to be typical or characteristic of the system, but small and regular enough to be explained well by a set of microscopic processes.

In the first top-down phase towards the bottom level, we must find the significant, relevant and salient properties, events and interactions, especially the crucial events responsible for butterfly effects, avalanches and cascades. We seek the concrete, precise and deterministic realization of abstract concepts. Many microscopic details are insignificant, irrelevant and inconsequential to macroscopic phenomena. In the second bottom-up phase towards the top level, you have to compare the results of the synthesis and simulation which the desired structure. | In the first top-down phase towards the bottom level, we must find the significant, relevant and salient properties, events and interactions, especially the crucial events responsible for butterfly effects, avalanches and cascades.

In a typical iteration of “synthetic microanalysis”, you start from the “top” and work your way down to the micro-level, constructing agent roles and interaction rules in just the way necessary to generate the behavior observed on “top”. This procedure can be iterated by stepwise refinement of agents and their interactions, which should include necessary changes in the environment, until the desired function is achieved. | In a typical iteration of “synthetic microanalysis”, you start from the “top” and work your way down to the micro-level, constructing agent roles and interaction rules in just the way necessary to generate the behavior observed on “top”.

In the next round, you start start again from the global structure or macroscopic pattern, and try to refine the possible underlying microstates and micromechanisms. Could these states and mechanisms lead to the desired large-scale structure? What kind of coordination, conflict-resolution and local guidance is needed additionally? What kind of roles and role-transitions are possible? | In the next round, you start start again from the global structure or macroscopic pattern, and try to refine the possible underlying microstates and micromechanisms.
