Motion and pinning of discrete interfaces

I study the motion of a discrete interface following the minimizing movement approach, describing an effective crystalline motion in the continuum. This motion can be compared with the continuous crystalline motion described by Almgren and Taylor highlighting additional pinning, velocity quantization and non-uniqueness effects.
