Member Function Documentation

void CglFlowCover::flowPreprocess ( const OsiSolverInterface & si )

Do the following tasks:

classify row types
indentify vubs and vlbs

This function is called by generateCuts(const OsiSolverInterface & si, OsiCuts & cs).

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

virtual

Generate Lifed Simple Generalized flow cover cuts for the model data contained in si.

The generated cuts are inserted into and returned in the collection of cuts cs.

Implements CglCutGenerator.

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

friend

A function that tests the methods in the CglFlowCover 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.

The documentation for this class was generated from the following file:
