Initialization
 NNCBoxSupportFunction (const CH_Matrix_Classes::Matrix &lb, const CH_Matrix_Classes::Matrix &ub, const CBout *cb=0, int incr=-1)
 intialize with lower bounds vector lb and upper bounds vector ub (and output options), both must be column vectors of the same length and lb<=ub componentwise, length 0 results in objective value 0
 
 ~NNCBoxSupportFunction ()
 
Implementations of MatrixFunctionOracle routines
int evaluate (const CH_Matrix_Classes::Matrix &current_point, CH_Matrix_Classes::Real relprec, CH_Matrix_Classes::Real &objective_value, std::vector< Minorant *> &minorants, PrimalExtender *&primal_extender)
 see MatrixFunctionOracle::evaluate()
 
virtual int apply_modification (const OracleModification &oracle_modification, const CH_Matrix_Classes::Matrix *new_center, const CH_Matrix_Classes::Matrix *old_center, bool &discard_objective_in_center, bool &discard_model, bool &discard_aggregates, MinorantExtender *&minorant_extender)
 see MatrixFunctionOracle::apply_modification() for the general use, here oracle_modification has a special role if it can be cast to an AMFModification More...
 
virtual bool check_correctness () const
 see MatrixFunctionOracle::check_correctness() (true only needed for debugging)
 
routines for querying data of the problem
const CH_Matrix_Classes::Matrixget_lower_bounds ()
 returns the column vector of lower bounds
 
const CH_Matrix_Classes::Matrixget_upper_bounds ()
 retunrs the column vector of upper bounds
 
routines for supporting input and output
void set_out (std::ostream *o=0, int pril=1)
 see ConicBundle::CBout
 
void set_cbout (const CBout *cb, int incr=-1)
 see ConicBundle::CBout
 
std::ostream & print_problem_data (std::ostream &out) const
 write the problem description to out so that it can be read again by read_problem_data()
 
std::istream & read_problem_data (std::istream &in)
 clear() and read the problem from in in the format written by print_problem_data()
 
std::ostream & print_problem_data_to_mfile (std::ostream &out, CH_Matrix_Classes::Integer blocknr) const
 undocumented highly volatile variant for external testing

virtual ~ModifiableOracleObject ()
 virtual destructor
 
- Public Member Functions inherited from ConicBundle::CBout
void clear_cbout ()
 reset to default settings (out=0,print_level=1)
 
 CBout (const CBout *cb=0, int incr=-1)
 calls set_cbout
 
 CBout (std::ostream *outp, int pl=1)
 initialize correspondingly
 
 CBout (const CBout &cb, int incr=0)
 copy constructor
 
virtual bool cb_out (int pl=-1) const
 Returns true if out!=0 and (pl<print_level), pl<0 should be used for WARNINGS and ERRORS only, pl==0 for usual output.
 
std::ostream & get_out () const
 If cb_out() returned true, this returns the output stream, but it will abort if called with out==0.
 
std::ostream * get_out_ptr () const
 returns the pointer to the output stream
 
int get_print_level () const
 returns the print_level
 
virtual int mfile_data (std::ostream &out) const
 writes problem data to the given outstream
 

Private Member Functions
