WebWe study techniques for deriving primal-dual methods, methods that explicitly maintain and update both primal and dual variables. Base splitting methods are limited to minimizing f(x) + g(x) or f(x) + g(x) + h(x). Primal-dual methods can solve a wider range of problems and … WebIn dual methods, such as FETI, the continuity of the solution across the subdomain interface is enforced by Lagrange multipliers. The FETI-DP method is hybrid between a dual and a primal method. Non-overlapping domain decomposition methods are also called iterative substructuring methods.
