Detailed Description

This class describes the core of the MIP problem, the variables/cuts in it as well as the matrix corresponding the core variables and cuts.

Core cuts and variables never leave the formulation.

Definition at line 31 of file BCP_problem_core.hpp.

Constructor & Destructor Documentation

BCP_problem_core::BCP_problem_core ( const BCP_problem_core &  )

private

The copy constructor is declared but not defined to disable it.

BCP_problem_core::BCP_problem_core

(

)

The default constructor creates an empty core description: no variables/cuts and an empty matrix.

BCP_problem_core::BCP_problem_core ( BCP_vec< BCP_var_core * > &  v, BCP_vec< BCP_cut_core * > &  c, BCP_lp_relax *&  m  )

inline

This constructor "takes over" the arguments.

The created core description will have the content of the arguments in its data members while the arguments lose their content.

Definition at line 65 of file BCP_problem_core.hpp.

References cuts, BCP_vec< T >::swap(), and vars.

BCP_problem_core::~BCP_problem_core

(

)

The desctructor deletes all data members.

Member Function Documentation

void BCP_problem_core::clear ( )

inlineprivate

Delete all data members.

This method purges the pointer vector members, i.e., deletes the object the pointers in the vectors point to.

BCP_problem_core& BCP_problem_core::operator= ( const BCP_problem_core &  )

private

The assignment operator is declared but not defined to disable it.

size_t BCP_problem_core::varnum ( ) const

inline

Return the number of variables in the core.

Definition at line 78 of file BCP_problem_core.hpp.

References BCP_vec< T >::size(), and vars.

size_t BCP_problem_core::cutnum ( ) const

inline

Return the number of cuts in the core.

Definition at line 80 of file BCP_problem_core.hpp.

References cuts, and BCP_vec< T >::size().

void BCP_problem_core::pack

(

BCP_buffer &

buf

)

const

Pack the contents of the core description into the buffer.

void BCP_problem_core::unpack

(

BCP_buffer &

buf

)

Unpack the contents of the core description from the buffer.

Member Data Documentation

BCP_vec<BCP_var_core*> BCP_problem_core::vars

A vector of pointers to the variables in the core of the problem.

These are the variables that always stay in the problem formulation.

BCP_vec<BCP_cut_core*> BCP_problem_core::cuts

A vector of pointers to the cuts in the core of the problem.

These are the cuts that always stay in the problem formulation.

Definition at line 51 of file BCP_problem_core.hpp.

Referenced by BCP_problem_core(), and cutnum().

BCP_lp_relax* BCP_problem_core::matrix

A pointer to the constraint matrix corresponding to the core variables and cuts.
