Web2 Optimized Restricted Additive Schwarz Methods Historically, domain decomposition methods were formulated at the continu-ous level. We consider a decomposition of the original domain Ω in (1) into two overlapping sub-domains Ω1 and Ω2, and we denote the interfaces by Γij = ∂Ωi ∩ Ωj, i 6= j, and the outer boundaries by ∂Ωj = ∂Ω ... Webthe optimized Schwarz methods on the optimal control problem is still open. Of course, other domain decomposition methods are also applicable, see for example [28] for FETI-DP methods; [26,27] for balancing Neumann–Neumann methods. For other type of domain decompositions and other type of governing equations, we refer the reader to [31].
