The classical approach to the problem uses convex analysis (Rockafellar, 1970) to derive first-order conditions for improvement around an a priori known steady-state solution to the optimization problem using periodic perturbation
The periodically inserted B zone (no-barrier zone) is regarded as the periodic perturbation

The role of periodic perturbation
is critical (as we shall see below) in 'resetting' the 'evolutionary clock', and can lead - as with Mediterranean ecosystems - to alternating oscillations between degradation and regeneration over time.
