Real ROL::Problem< Real >::checkLinearity	(	bool	printToStream = `false`,
		std::ostream &	outStream = `std::cout`
	)		const

Check if user-supplied linear constraints are affine.

This function computes the error

for each user-supplied linear constraint and returns the maximum.

Parameters

[in,out]	outStream	user supplied std::ostream

template<typename Real>

void ROL::Problem< Real >::checkVectors	(	bool	printToStream = `false`,
		std::ostream &	outStream = `std::cout`
	)		const

Run vector checks for user-supplied vectors.

Parameters

[in]	printToStream	determines whether to print to the supplied std::ostream
[in,out]	outStream	user supplied std::ostream

template<typename Real >

void ROL::Problem< Real >::checkDerivatives	(	bool	printToStream = `false`,
		std::ostream &	outStream = `std::cout`,
		const Ptr< Vector< Real >> &	x0 = `nullPtr`,
		Real	scale = `Real(1)`
	)		const

Run derivative checks for user-supplied objective function and constraints.

Parameters

[in]	printToStream	determines whether to print to the supplied std::ostream
[in,out]	outStream	user supplied std::ostream

		const Ptr< Vector< Real >> &	x0 = `nullPtr`,
		Real	scale = `Real(1)`
	)		const

Run vector, linearity and derivative checks for user-supplied vectors, objective function and constraints.

Parameters

[in]	printToStream	determines whether to print to the supplied std::ostream
[in,out]	outStream	user supplied std::ostream

Definition at line 644 of file algorithm/ROL_Problem_Def.hpp.
