- “A selection criterion that determines which of the possible state transitions corresponding to different operators will actually take place” (F. HEYLIGHEN, 1990a, p.426).
- “Dynamical constraints usually have the form of either:
1) differential (or difference) equations, relating the predicted state transition (time derivate of the state) to the present state
2) conservation principles, stating that a certain global property of the system (e.g. energy) must be conserved during the transition, or
3) variation or optimization. principles, stating that the transition will occur that minimizes (or maximizes) a certain function of the transition parameters (Ibid).
- “A dynamical constraint corresponds to a distinction between an allowed state transition and an impossible one” (Ibid, p.427).
