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.

Member Function Documentation

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

Clone.

Reimplemented from OsiSimpleInteger.

OsiUsesBiLinear& OsiUsesBiLinear::operator= ( const OsiUsesBiLinear rhs  ) 

Assignment operator.

Reimplemented from OsiSimpleInteger.

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

Infeasibility - large is 0.5.

Reimplemented from OsiSimpleInteger.

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.

Reimplemented from OsiSimpleInteger.

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.

Reimplemented from OsiSimpleInteger.

void OsiUsesBiLinear::addBiLinearObjects ( OsiSolverLink solver  ) 

Add all bi-linear objects.
