Detailed Description

Define Special Linked Ordered Sets.

New style

members and weights may be stored in SOS object

This is for y and x*f(y) and z*g(y) etc

Member Function Documentation

clone()

virtual OsiObject* OsiLink::clone ( ) const

virtual

Clone.

operator=()

OsiLink& OsiLink::operator=

(

const OsiLink &

rhs

)

infeasibility()

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

virtual

Infeasibility - large is 0.5.

feasibleRegion()

virtual double OsiLink::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* OsiLink::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 OsiLink::resetSequenceEtc ( int  numberColumns, const int *  originalColumns  )

virtual

Redoes data when sequence numbers change.

numberLinks()

int OsiLink::numberLinks ( ) const

inline

Number of links for each member.

Definition at line 658 of file CbcLinked.hpp.

canDoHeuristics()

virtual bool OsiLink::canDoHeuristics ( ) const

inlinevirtual

Return true if object can take part in normal heuristics.

Definition at line 665 of file CbcLinked.hpp.

boundBranch()

virtual bool OsiLink::boundBranch ( ) const

inlinevirtual

Return true if branch should only bound variables.

Definition at line 671 of file CbcLinked.hpp.
