Constructor & Destructor Documentation

OsiOldLink::OsiOldLink ( )
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::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

virtual OsiObject* OsiOldLink::clone ( ) const [virtual]

Clone.

OsiOldLink& OsiOldLink::operator= ( const OsiOldLink rhs)
virtual double OsiOldLink::infeasibility ( const OsiBranchingInformation *  info,
int &  whichWay 
) const [virtual]

Infeasibility - large is 0.5.

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.

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.

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

Redoes data when sequence numbers change.

int OsiOldLink::numberLinks ( ) const [inline]

Number of links for each member.

Definition at line 494 of file CbcLinked.hpp.

virtual bool OsiOldLink::canDoHeuristics ( ) const [inline, virtual]

Return true if object can take part in normal heuristics.

Definition at line 500 of file CbcLinked.hpp.

virtual bool OsiOldLink::boundBranch ( ) const [inline, virtual]

Return true if branch should only bound variables.
