Detailed Description
template<typename Real>
class ROL::DynamicObjective< Real >
Defines the time-dependent objective function interface for simulation-based optimization. Computes time-local contributions of value, gradient, Hessian-vector product etc to a larger composite objective defined over the simulation time. In contrast to other objective classes Objective_TimeSimOpt has a default implementation of value which returns zero, as time-dependent simulation based optimization problems may have an objective value which depends only on the final state of the system.
Often in applications, the objective is separable into a state objective and a control objective so the state-control cross terms in the Hessian are zero.
A typical use case involves quadratic terms for the state and control, such that all of the diagonal blocks of the Hessian are nonzero and the off-diagonal blocks are zero.
