In this paper we consider the convergence theory for an all-at-once multigrid method for a distributed optimal control problem. Such an analysis has been recently done [J. Schöberl, R. Simon, and W.

The convergence of Markov chain-based Monte Carlo linear solvers using the Ulamvon Neumann algorithm for a linear system of the form x = H x + b is investigated in this paper. We analyze the ...
