Member Function Documentation

clone()

virtual CbcObject * CbcSimpleIntegerFixed::clone ( ) const

virtual

Clone.

Reimplemented from CbcSimpleInteger.

operator=()

CbcSimpleIntegerFixed & CbcSimpleIntegerFixed::operator=

(

const CbcSimpleIntegerFixed &

rhs

)

infeasibility()

virtual double CbcSimpleIntegerFixed::infeasibility ( int & preferredWay ) const

virtual

Infeasibility - large is 0.5.

createBranch()

virtual CbcBranchingObject * CbcSimpleIntegerFixed::createBranch ( OsiSolverInterface * solver, const OsiBranchingInformation * info, int way )

virtual

Creates a branching object.

The preferred direction is set by way, -1 for down, +1 for up. Create a branching object and indicate which way to branch first.

The branching object has to know how to create branches (fix variables, etc.)
