Fig. 13.6 Dynamic models of interaction designed world/context
compatibility, this simplifies the task to link the new function to the past one.
Back in K, this leads to a new connected component associated to the set F(t + 1)
but also to other connected components associated to the functions that were
This second process actually leads to the emergence of complex but separate
connected components in K.
13.4.2 Using the Model to Interpret Some Dynamic
Situations
1. A first situation to analyze is the “imperfect design” of generic technology: in
part 2, we made the hypothesis that the designer would be able to address all the
edges required. Suppose now that there is a budget limit. Then it is possible that
the budget is not sufficient to create a spanning tree for the C-graph. Or the
designer will select a subset of F to get only a partial generacity. We say that
the design of GT is imperfect. Interestingly enough, these behaviors can be
represented in the model above. They all fall in the second situation, either
because the set F is restricted in advance, or because the new edges to be
designed can only address a subset of F., due to cost reasons. It explains how
over time, one can have the stabilization of a connected subgraph without
relation with active parametres of F.
2. The dynamic model also leads to come back to evolutionary models in a richer
way: instead of considering a selection process based on one given state of
nature, one can represent the evolutions of probable states of nature, ie as subsets
of F. In this extended evolutionary model, one can find partial genericity
