The construction of reduced order models for dynamical systems using
proper orthogonal decomposition (POD) is based on the information
contained in so-called snapshots. These provide the spatial
distribution of the dynamical system at discrete time instances.
This work is devoted to optimizing the choice of these time
instances in such a manner that the error between the POD-solution
and the trajectory of the dynamical system is minimized. First and
second order optimality systems are given. Numerical examples
illustrate that the proposed criterion is sensitive with respect to
the choice of the time instances and further they demonstrate the
feasibility of the method in determining optimal snapshot locations
for concrete diffusion equations.
