Constructor & Destructor Documentation

QuasiNewton_U()

template<typename Real>

ROL::ROL::QuasiNewton_U< Real >::QuasiNewton_U ( ParameterList & parlist, const Ptr< Secant< Real > > & secant = nullPtr )

inline

Constructor.

Constructor to build a QuasiNewton object with a user-defined secant object. Algorithmic specifications are passed in through a ROL::ParameterList.

Parameters

[in]	parlist	is a parameter list containing algorithmic specifications
[in]	secant	is a user-defined secant object
