The core problem is that the convergence rates of these ODE models can be misleading due to time rescaling. The paper introduces the concept of 'essential convergence rate' to provide a more robust and meaningful measure of convergence. The significance lies in establishing a lower bound on the convergence rate achievable by discretizing the ODE, thus providing a more reliable way to compare and evaluate different optimization methods based on their continuous-time representations.
