Detailed Description

AllDifferent Cut Generator Class This has a number of sets.

All the members in each set are general integer variables which have to be different from all others in the set.

At present this only generates column cuts

At present it is very primitive compared to proper CSP implementations

CglAllDifferent::CglAllDifferent ( )

Default constructor.

CglAllDifferent::CglAllDifferent	(	int	numberSets,
		const int *	starts,
		const int *	which
	)

Useful constructot.

CglAllDifferent::CglAllDifferent ( const CglAllDifferent & )

Copy constructor.

virtual CglAllDifferent::~CglAllDifferent ( )

virtual

Destructor.

Member Function Documentation

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

virtual

This fixes (or reduces bounds) on sets of all different variables.

Implements CglCutGenerator.

virtual CglCutGenerator* CglAllDifferent::clone ( ) const

virtual

Clone.

Implements CglCutGenerator.

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

Assignment operator.

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

virtual

Create C++ lines to get to current state.

Reimplemented from CglCutGenerator.

virtual void CglAllDifferent::refreshSolver ( OsiSolverInterface * solver )

virtual

This can be used to refresh any inforamtion.

Reimplemented from CglCutGenerator.

virtual bool CglAllDifferent::mayGenerateRowCutsInTree ( ) const

inlinevirtual

Returns true if may generate Row cuts in tree (rather than root node).

Used so know if matrix will change in tree. Really meant so column cut generators can still be active without worrying code. Default is true

Reimplemented from CglCutGenerator.
