Detailed Description

Define a single variable class which is involved with OsiBiLinear objects.

This is used so can make better decision on where to branch as it can look at all objects.

This version sees if it can re-use code from OsiSimpleInteger even if not an integer variable. If not then need to duplicate code.

Constructor & Destructor Documentation

OsiUsesBiLinear::OsiUsesBiLinear

(

)

Default Constructor.

OsiUsesBiLinear::OsiUsesBiLinear	(	const OsiSolverInterface *	solver,
		int	iColumn,
		int	type
	)

Useful constructor - passed solver index.

OsiUsesBiLinear::OsiUsesBiLinear	(	int	iColumn,
		double	lower,
		double	upper,
		int	type
	)

Useful constructor - passed solver index and original bounds.

OsiUsesBiLinear::OsiUsesBiLinear	(	const OsiSimpleInteger &	rhs,
		int	type
	)

Useful constructor - passed simple integer.

OsiUsesBiLinear::OsiUsesBiLinear

(

const OsiUsesBiLinear &

rhs

)

Copy constructor.

virtual OsiUsesBiLinear::~OsiUsesBiLinear ( )

virtual

Destructor.

Member Function Documentation

virtual OsiObject* OsiUsesBiLinear::clone ( ) const

virtual

Clone.

OsiUsesBiLinear& OsiUsesBiLinear::operator=

(

const OsiUsesBiLinear &

rhs

)

Assignment operator.

virtual double OsiUsesBiLinear::infeasibility ( const OsiBranchingInformation *  info, int &  whichWay  ) const

virtual

Infeasibility - large is 0.5.

virtual OsiBranchingObject* OsiUsesBiLinear::createBranch ( OsiSolverInterface *  solver, const OsiBranchingInformation *  info, int  way  ) const

virtual

Creates a branching object.

The preferred direction is set by way, 0 for down, 1 for up.

virtual double OsiUsesBiLinear::feasibleRegion ( OsiSolverInterface *  solver, const OsiBranchingInformation *  info  ) const

virtual

Set bounds to fix the variable at the current value.

Given an current value, set the lower and upper bounds to fix the variable. Returns amount it had to move variable.

void OsiUsesBiLinear::addBiLinearObjects

(

OsiSolverLink *

solver

)

Add all bi-linear objects.
