We use a discrete approximation of the motion by crystalline curvature to define an evolution of sets from a single point (nucleation) following a criterion of %26quot;maximization%26quot; of the perimeter, formally giving a backward version of the motion by crystalline curvature. This evolution depends on the approximation chosen.
