Abstract

In this manuscript, we describe effective solvers for the optimal control of stabilized convectiondiffusion

whether the discretize-then-optimize or optimize-then-discretize approach for this problem is used. We then derive

the Bramble-Pasciak Conjugate Gradient method. The key components of both preconditioners are an accurate mass

this latter approximation. We present numerical results to illustrate that these preconditioners result in convergence

a range of problems.
