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(MRVMBidder bidder,
                                                                MRVMRegionsMap.Region region,
                                                                MRVMBand band)

Throws:

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

getXVariables

public java.util.Set<edu.harvard.econcs.jopt.solver.mip.Variable> getXVariables(MRVMBidder bidder)

getValueVariable

public edu.harvard.econcs.jopt.solver.mip.Variable getValueVariable(MRVMBidder bidder)

getBiggestPossibleValue

public double getBiggestPossibleValue()

Returns:
