Detailed Description

template<class Real>
class ROL::Constraint< Real >

Defines the general constraint operator interface.

ROL's constraint interface is designed for Fréchet differentiable operators \(c:\mathcal{X} \rightarrow \mathcal{C}\), where \(\mathcal{X}\) and \(\mathcal{C}\) are Banach spaces. The constraints are of the form

\[ c(x) = 0 \,. \]

The basic operator interface, to be implemented by the user, requires:

It is strongly recommended that the user additionally overload:

The user may also overload:

Parameters
[out]v1is the optimization-space component of the result
[out]v2is the dual constraint-space component of the result
[in]b1is the dual optimization-space component of the right-hand side
[in]b2is the constraint-space component of the right-hand side

The default implementation is the preconditioned generalized minimal residual (GMRES) method, which enables the use of nonsymmetric preconditioners.
