Asymptotic and Discrete Concepts for Optimal Control in Radiative Transfer

Optimal control problems for radiative transfer and for approximate models are con-sidered. Following the approach first discretize, then optimize, the discrete SPN approxi-mations are for the first time derived exactly, which can be used to study optimal control on reduced order models. Combining asymptotic analysis and the adjoint calculus yields diffusive-type approximations for the adjoint radiative transport equation in the spirit of the approach first optimize, then discretize
