      1) Residual minimization scheme is the new Adjoint Solver stabilization scheme, available from v19.2 onwards 2) with this, The overall adjoint residual most certainly will decrease, this is a unique benefit compared to the other available schemes 3) However, this scheme is expensive with regard to memory, when it is enabled each main iteration consists of multiple sub-iterations, where one sub-iteration is equivalent to one normal adjoint iteration 4) usually, it is recommended to switch ON this scheme after running some initial iterations with some other schemes ( Dissipation scheme )
