Detailed Description

template<typename Real>
class ROL::DynamicTrackingObjective< Real >

Defines the time-local contribution to a quadratic tracking objective.

\[ f_k(u,z) = \frac{1}{2} \int\limits_{t_{k-1}}^{t_k} \| u(t)-\tilde u(t)\|^2 + \alpha \|z(t)\^2\,\mathm{d}t \] 

  Currently approximates the integral with the trapezoidal rule.
