virtual bool Ipopt::InexactNormalTerminationTester::InitializeImpl	(	const OptionsList &	options,
		const std::string &	prefix
	)

virtual

static

Methods for IpoptType.

virtual bool Ipopt::InexactNormalTerminationTester::InitializeSolve ( )

virtual

Method for initializing for the next iterative solve.

This must be call before the test methods are called.

Implements Ipopt::IterativeSolverTerminationTester.

virtual ETerminationTest Ipopt::InexactNormalTerminationTester::TestTermination	(	Index	ndim,
		const Number *	sol,
		const Number *	resid,
		Index	iter,
		Number	norm2_rhs
	)

virtual

This method checks if the current soltion of the iterative linear solver is good enough (by returning the corresponding satisfied termination test), or if the Hessian should be modified.

The input is the dimension of the augmented system, the current solution vector of the augmented system, the current residual vector.

Implements Ipopt::IterativeSolverTerminationTester.

virtual void Ipopt::InexactNormalTerminationTester::Clear ( )

virtual

This method can be called after the Solve is over and we can delete anything that has been allocated to free memory.

Implements Ipopt::IterativeSolverTerminationTester.

virtual Index Ipopt::InexactNormalTerminationTester::GetSolverIterations ( ) const

inlinevirtual

Return the number of iterative solver iteration from the most recent solve.

Implements Ipopt::IterativeSolverTerminationTester.
