#include <BonIpoptInteriorWarmStarter.hpp>

List of all members.

Public Member Functions
bool	UpdateStoredIterates (Ipopt::AlgorithmMode mode, const Ipopt::IpoptData &ip_data, Ipopt::IpoptCalculatedQuantities &ip_cq)
	Method for possibly storing another iterate during the current optimizatin for possible use for a warm start for a new problem.
bool	Finalize ()
	Method for doing whatever needs to be done after the parent NLP has been solved.
bool	WarmStartIterate (Ipopt::Index n, const Ipopt::Number *x_l_new, const Ipopt::Number *x_u_new, Ipopt::IteratesVector &warm_start_iterate)
	Method for computing the initial point based on the stored information.
Constructors/Destructors
	IpoptInteriorWarmStarter (Ipopt::Index n, const Ipopt::Number *x_L, const Ipopt::Number *x_u, Ipopt::Number nlp_lower_bound_inf, Ipopt::Number nlp_upper_bound_inf, bool store_several_iterates)
	Constructor.
	~IpoptInteriorWarmStarter ()
	Default destructor.
Private Member Functions
Default Compiler Generated Methods
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.
	IpoptInteriorWarmStarter ()
	Default constructor.
	IpoptInteriorWarmStarter (const IpoptInteriorWarmStarter &)
	Copy Constructor.
void	operator= (const IpoptInteriorWarmStarter &)
	Overloaded Equals Operator.
Private Attributes
Ipopt::Number	nlp_lower_bound_inf_
	Value for a lower bound that denotes -infinity.
Ipopt::Number	nlp_upper_bound_inf_
	Value for a upper bound that denotes infinity.
bool	store_several_iterates_
	Flag indicating whether more than one iterate is to be stored.
Copy of the bounds for the previously solved NLP. This is
required to find out the remapping for fixed variables, and it might also help to see how large the perturbation of the new problem is.
Ipopt::Index	n_
Ipopt::Number *	x_l_prev_
Ipopt::Number *	x_u_prev_
Selected Iterates and quantities from the previous
optimization
