A splitting-based KPIK method for eddy current optimal control problems in an all-at-once approach
Min-Li Zeng, Martin Stoll
In this paper, we focus on efficient methods to solve discretized linear systems obtained from eddy current optimal control problems in an all-at-once approach. We construct a new…
