Member Function Documentation

template<typename Real >

int ROL::Solver< Real >::solve	(	const Ptr< StatusTest< Real >> &	status = `nullPtr`,
		bool	combineStatus = `true`
	)

Solve optimization problem with no iteration output.

Parameters

[in]	status	is a user-defined StatusTest
[in]	combineStatus	if true, the user-defined StatusTest will be combined with the default StatusTest

Definition at line 66 of file ROL_Solver_Def.hpp.

template<typename Real >

int ROL::Solver< Real >::solve	(	std::ostream &	outStream,
		const Ptr< StatusTest< Real >> &	status = `nullPtr`,
		bool	combineStatus = `true`
	)

Solve optimization problem.

Parameters

[in]	outStream	is the output stream to collect iteration history
[in]	status	is a user-defined StatusTest
[in]	combineStatus	if true, the user-defined StatusTest will be combined with the default StatusTest

template<typename Real >

Ptr< const AlgorithmState< Real > > ROL::Solver< Real >::getAlgorithmState ( void ) const

Return the AlgorithmState.

template<typename Real >

void ROL::Solver< Real >::reset ( void )

Reset both Algorithm and Step.

This function will reset the AlgorithmState and reinitialize the Step. This function does not permit changing the Step specified upon construction. To change the Step, reinitialize the OptimizationSolver.
