virtual CglLiftAndProject::~CglLiftAndProject ( )

virtual

Destructor.

Member Function Documentation

virtual void CglLiftAndProject::generateCuts	(	const OsiSolverInterface &	si,
		OsiCuts &	cs,
		const CglTreeInfo	info = `CglTreeInfo()`
	)

virtual

Generate lift-and-project cuts for the model of the solver interface, si.

Insert the generated cuts into OsiCut, cs.

Implements CglCutGenerator.

double CglLiftAndProject::getBeta ( ) const

inline

Get the normalization : Either beta=+1 or beta=-1.

Definition at line 30 of file CglLiftAndProject.hpp.

void CglLiftAndProject::setBeta ( int oneOrMinusOne )

inline

Set the normalization : Either beta=+1 or beta=-1.

Default value is 1.

Definition at line 37 of file CglLiftAndProject.hpp.

virtual CglCutGenerator* CglLiftAndProject::clone ( ) const

virtual

Clone.

Implements CglCutGenerator.

CglLiftAndProject& CglLiftAndProject::operator= ( const CglLiftAndProject & rhs )

Assignment operator.

virtual std::string CglLiftAndProject::generateCpp ( FILE * fp )

virtual

Create C++ lines to get to current state.

Reimplemented from CglCutGenerator.

Friends And Related Function Documentation

void CglLiftAndProjectUnitTest	(	const OsiSolverInterface *	siP,
		const std::string	mpdDir
	)

friend

A function that tests the methods in the CglLiftAndProject class.

The only reason for it not to be a member method is that this way it doesn't have to be compiled into the library. And that's a gain, because the library should be compiled with optimization on, but this method should be compiled with debugging.
