-- `schur_subproblem_solver::Module = DefaultLinearSolver` \
-   Linear solver used for solving subproblem. Valid values are: {`MadNLPUmfpack`, `MadNLPMa27`, `MadNLPMa57`, `MadNLPMa97`, `MadNLPMumps`}.

-- `schur_custom_partition::Bool = false` \
-   If `false`, Schur solver automatically detects the partition using `Metis`. If `true`, the partition information given in `schur_part` is used. `schur_num_parts` and `schur_part` should be properly set by the user. When using with `Plasmo`, `schur_num_parts` and `schur_part` are automatically set by the `Plasmo` interface.

-   Number of parts (excluding the parent node). Valid range is ``[1,\infty)``
-- `schur_part::Vector{Int} = Int[]` \
-   Custom partition information in a vector form. The parent node should be labeled as `0`. Only valid if `schur_custom_partition` is `true`.

-    Custom partition information in a vector form. Only valid if `schwar_custom_partition` is `true`.
-- `schwarz_num_parts_upper::Int = 0` \
-    Number of parts in upper level partition. If `schwarz_num_parts_upper!=0`, a bilevel partitioning scheme is used. Valid range is ``[1,\infty)``
-- `schwarz_part_upper::Vector{Int} = Int[]` \
-    Custom partition for the upper level partition.
-- `schwarz_fully_improve_subproblem_solver::Bool = true` \
-    If `true`, the subproblem solvers are fully improved when the linear solver is initialized.
-- `schwarz_max_expand_factor::Int = 4` \
-    The size of overlap is fully saturated when the `improve!` is called `schwarz_max_expand_factor-1` times. Valid range is ``[2,\infty)``.
