OsiOldLink() [2/4]

OsiOldLink::OsiOldLink	(	const OsiSolverInterface *	solver,
		int	numberMembers,
		int	numberLinks,
		int	first,
		const double *	weights,
		int	setNumber
	)

Useful constructor - A valid solution is if all variables are zero apart from k*numberLink to (k+1)*numberLink-1 where k is 0 through numberInSet-1.

The length of weights array is numberInSet. For this constructor the variables in matrix are the numberInSet*numberLink starting at first. If weights null then 0,1,2..

OsiOldLink() [3/4]

OsiOldLink::OsiOldLink	(	const OsiSolverInterface *	solver,
		int	numberMembers,
		int	numberLinks,
		int	typeSOS,
		const int *	which,
		const double *	weights,
		int	setNumber
	)

Useful constructor - A valid solution is if all variables are zero apart from k*numberLink to (k+1)*numberLink-1 where k is 0 through numberInSet-1.

The length of weights array is numberInSet. For this constructor the variables are given by list - grouped. If weights null then 0,1,2..

Member Function Documentation

clone()

virtual OsiObject* OsiOldLink::clone ( ) const

virtual

Clone.

operator=()

OsiOldLink& OsiOldLink::operator=

(

const OsiOldLink &

rhs

)

infeasibility()

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

virtual

Infeasibility - large is 0.5.

feasibleRegion()

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

virtual

Set bounds to fix the variable at the current (integer) value.

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

createBranch()

virtual OsiBranchingObject* OsiOldLink::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.

resetSequenceEtc()

virtual void OsiOldLink::resetSequenceEtc ( int  numberColumns, const int *  originalColumns  )

virtual

Redoes data when sequence numbers change.

numberLinks()

int OsiOldLink::numberLinks ( ) const

inline

Number of links for each member.

Definition at line 506 of file CbcLinked.hpp.

canDoHeuristics()

virtual bool OsiOldLink::canDoHeuristics ( ) const

inlinevirtual

Return true if object can take part in normal heuristics.

Definition at line 513 of file CbcLinked.hpp.

boundBranch()

virtual bool OsiOldLink::boundBranch ( ) const

inlinevirtual

Return true if branch should only bound variables.
