Gradient-descent mapping on the potential energy hypersurface locates the relevant inherent structures (local minima) during the course of MC or MD simulation runs for continuum models. Observing temporal sequences of such inherent structures is proposed as a way to clarify relaxation processes near the glass transition. Also, the importance to execute parallel MC and MD runs on the same glass model is stressed to establish a quantitative time scaling for the two to permit comparison of relaxation results.
