Default Compiler Generated Methods

(Hidden to avoid implicit creation/calling).

These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.

Set up the augmented system and solve it for a set of given right hand side - implementation for GenTMatrices and SymTMatrices.

Reimplemented from Ipopt::AugSystemSolver.

virtual Index Ipopt::GenAugSystemSolver::NumberOfNegEVals ( ) const
virtual

Number of negative eigenvalues detected during last solve.

Returns the number of negative eigenvalues of the most recent factorized matrix. This must not be called if the linear solver does not compute this quantities (see ProvidesInertia).

Request to increase quality of solution for next solve.

Ask underlying linear solver to increase quality of solution for the next solve (e.g. increase pivot tolerance). Returns false, if this is not possible (e.g. maximal pivot tolerance already used.)
