TQpResidual

The Residuals class calculates and stores the quantities that appear
on the right-hand side of the linear systems that arise at each
interior-point iteration. These residuals can be partitioned into
two fundamental categories: the components arising from the linear
equations in the KKT conditions, and the components arising from the
complementarity conditions.

Function documentation

TQpResidual()
 Constructor
TQpResidual(Int_t nx, Int_t my, Int_t mz, TVectorD& ixlow, TVectorD& ixupp, TVectorD& iclow, TVectorD& icupp)
 Constructor
TQpResidual(const TQpResidual& another)
 Copy constructor
void CalcResids(TQpDataBase* problem, TQpVar* vars)
 Calculate residuals, their norms, and duality complementarity gap,
 given a problem and variable set.
void Add_r3_xz_alpha(TQpVar* vars, Double_t alpha)
 Modify the "complementarity" component of the residuals, by adding the pairwise
 products of the complementary variables plus a constant alpha to this term.
void Set_r3_xz_alpha(TQpVar* vars, Double_t alpha)
 Set the "complementarity" component of the residuals to the pairwise products of
 the complementary variables plus a constant alpha .
void Clear_r3()
 set the complementarity component of the residuals to 0.
void Clear_r1r2()
 set the noncomplementarity components of the residual (the terms arising from
 the linear equalities in the KKT conditions) to 0.
void Project_r3(Double_t rmin, Double_t rmax)
 Perform the projection operation required by Gondzio algorithm: replace each
 component r3_i of the complementarity component of the residuals by r3p_i-r3_i,
 where r3p_i is the projection of r3_i onto the box [rmin, rmax]. Then if the
 resulting value is less than -rmax, replace it by -rmax.
Bool_t ValidNonZeroPattern()
 Check if vector elements as selected through array indices are non-zero
void GondzioProjection(TVectorD& v, Double_t rmin, Double_t rmax)
 Replace each component r3_i of the complementarity component of the residuals
 by r3p_i-r3_i, where r3p_i is the projection of r3_i onto the box [rmin, rmax].
 Then if the resulting value is less than -rmax, replace it by -rmax.
