Dynamic System Adaptation by Constraint Orchestration
L.P.J. Groenewegen & E.P. de Vink

For Paradigm models, evolution is just-in-time specified coordination
conducted by a special reusable component McPal. Evolution can be
treated consistently and on-the-fly through Paradigm's constraint
orchestration, also for originally unforeseen evolution. UML-like
diagrams visually supplement such migration, as is illustrated for the
case of a critical section solution evolving into a pipeline
architecture.
