Method Detail

appendToMip

public void appendToMip(edu.harvard.econcs.jopt.solver.IMIP mip)

Adds the generated variables and constraints to an existing MIP instance. Furthermore, this implementation of a PartialMip adds the objective term to the MIP

Overrides:

appendToMip in class PartialMIP

appendConstraintsToMip

public void appendConstraintsToMip(edu.harvard.econcs.jopt.solver.IMIP mip)

Overrides:

appendConstraintsToMip in class PartialMIP

appendVariablesToMip

public void appendVariablesToMip(edu.harvard.econcs.jopt.solver.IMIP mip)

Overrides:

appendVariablesToMip in class PartialMIP

getXVariable

public edu.harvard.econcs.jopt.solver.mip.Variable getXVariable(SRVMBidder bidder,
                                                                SRVMBand band)

Throws:

java.lang.NullPointerException - if the requested variable is not stored.

getVmVariable

public edu.harvard.econcs.jopt.solver.mip.Variable getVmVariable(SRVMBidder bidder,
                                                                 SRVMBand band)

getVoVariable

public edu.harvard.econcs.jopt.solver.mip.Variable getVoVariable(SRVMBidder bidder,
                                                                 SRVMBand band)

getBiggestPossibleValue

public double getBiggestPossibleValue()

Returns:

getScalingFactor

public double getScalingFactor()

Returns:
