Method Detail

gammaFactor

public java.math.BigDecimal gammaFactor(MRVMRegionsMap.Region r,
                                        java.util.Set<MRVMLicense> bundle)

Calculates the gamma factor, as explained in the model writeup.
The gamma factor represents a bidder-specific discount of the the regional (omega) values.

Specified by:

gammaFactor in class MRVMBidder

Parameters:

r - Not required for gamma calculation of national bidder and will be ignored

bundle - The complete bundle (not only containing the licenses of r).

gammaFactors

public java.util.Map<MRVMRegionsMap.Region,java.math.BigDecimal> gammaFactors(java.util.Set<MRVMLicense> bundle)

Calculates the gamma factors for all regions. For explanations of the gamma factors, see MRVMBidder.gammaFactor(MRVMRegionsMap.Region, Set)

As gamma is not dependent on the region for national bidders, the returned map will contain the same value for all keys, i.e. the same gamma for all regions

Specified by:

gammaFactors in class MRVMBidder

Parameters:

bundle - The bundle for which the discounts will be calculated.

getKMax

public int getKMax()

getGamma

public java.math.BigDecimal getGamma(int uncoveredRegions)

Reads the gammavalue form the stored map. If uncoveredRegions greater than getKMax(), then the value for kMax is returned (see model writeup for explanation).

Parameters:

uncoveredRegions - the number of regions that are uncovered

Returns:

the gamma value for the number of uncovered regions

drawSimilarBidder

public MRVMNationalBidder drawSimilarBidder(RNGSupplier rngSupplier)

Specified by:

drawSimilarBidder in class SATSBidder

getValueFunction

public <T extends BiddingLanguage> T getValueFunction(java.lang.Class<T> type,
                                                      RNGSupplier rngSupplier)
                                               throws UnsupportedBiddingLanguageException

Overrides:

Throws:

UnsupportedBiddingLanguageException

hashCode

public int hashCode()

Overrides:

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class MRVMBidder

bidderTypeSpecificDemandQueryMIPAdjustments

protected void bidderTypeSpecificDemandQueryMIPAdjustments(MRVM_MIP mip)

Description copied from class: MRVMBidder

Allows a specific bidder type (subclass) to change the demand query mip before execution. I.e. restrict demand query result to items where the bidder is interested in.

Specified by:

bidderTypeSpecificDemandQueryMIPAdjustments in class MRVMBidder
