Member Function Documentation

void SmallIP_DecompApp::createModels ( )

Referenced by SmallIP_DecompApp().

virtual int SmallIP_DecompApp::generateInitVars ( DecompVarList & initVars )

virtual

Initialize the dual vector for PhaseII of PC.

The user is passed a reference to the internal data and can manipulate it directly.

This is only called when dual stabilization is used, i.e., when m_param.DualStab > 0, at the first iteration of PhaseII of PC. The vector is immediately smoothed with the initial restricted master duals. By default, the restricted mater is used as the initial dual and, therefore, no smoothing occurs in the first iteration.

Reimplemented from DecompApp.
