Method Summary

Modifier and Type	Method	Description
java.math.BigDecimal	calculateValue(org.marketdesignresearch.mechlib.core.Bundle bundle)	Returns the value this bidder has for a specific bundle.
protected boolean	canEqual(java.lang.Object other)
SRVMBidder	drawSimilarBidder(RNGSupplier rngSupplier)
boolean	equals(java.lang.Object o)
java.util.Map<java.lang.String,java.math.BigDecimal>	getBaseValues()
java.util.LinkedHashSet<org.marketdesignresearch.mechlib.core.Bundle>	getBestBundles(org.marketdesignresearch.mechlib.core.price.Prices prices, int maxNumberOfBundles, boolean allowNegative)
java.math.BigDecimal	getBidderStrength()	This random value is used exclusively in {SRVMBidderSetup.drawBaseValues(SRVMWorld, BigDecimal, RNGSupplier), but stored in the bidder for easier analysis. Its mean is typically 1. Note that the bidder strength is not the only random influence on the base values, hence a high bidder strength does not imply that a bidder is stronger than others, it simply makes it more likely.
java.math.BigDecimal	getInterbandSynergyValue()
java.util.Map<java.lang.String,java.math.BigDecimal>	getIntrabandSynergyFactors()
java.util.Map<java.lang.String,java.lang.Integer>	getSynergyThreshold()
<T extends BiddingLanguage> T	getValueFunction(java.lang.Class<T> clazz, RNGSupplier rngSupplier)
SRVMWorld	getWorld()
int	hashCode()
void	refreshReference(World world)	To prevent from creating too many identical world instances, worlds are not serialized and deserialized with the bidder As a temporary solution, the world instance is re-added after deserialization by calling this method. This method will be removed in a later version and be done automatically during deserialization.

Method Detail

getWorld

public SRVMWorld getWorld()

Specified by:

getWorld in class SATSBidder

Returns:

World to which this bidder belongs. The implementing Bidder class, overriding this method, should return a world type corresponding to the specific model.

getBidderStrength

public java.math.BigDecimal getBidderStrength()

This random value is used exclusively in {SRVMBidderSetup.drawBaseValues(SRVMWorld, BigDecimal, RNGSupplier), but stored in the bidder for easier analysis.
Its mean is typically 1.

Note that the bidder strength is not the only random influence on the base values, hence a high bidder strength does not imply that a bidder is stronger than others, it simply makes it more likely.

Returns:

the bidder strength

getSynergyThreshold

public java.util.Map<java.lang.String,java.lang.Integer> getSynergyThreshold()

getBaseValues

public java.util.Map<java.lang.String,java.math.BigDecimal> getBaseValues()

getIntrabandSynergyFactors

public java.util.Map<java.lang.String,java.math.BigDecimal> getIntrabandSynergyFactors()

getInterbandSynergyValue

public java.math.BigDecimal getInterbandSynergyValue()

calculateValue

public java.math.BigDecimal calculateValue(org.marketdesignresearch.mechlib.core.Bundle bundle)

Description copied from class: SATSBidder

Returns the value this bidder has for a specific bundle.

Specified by:

calculateValue in class SATSBidder

Parameters:

bundle - the bundle for which the value is asked

Returns:

bidder specific value for this bundle

drawSimilarBidder

public SRVMBidder drawSimilarBidder(RNGSupplier rngSupplier)

Specified by:

drawSimilarBidder in class SATSBidder

getValueFunction

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

Specified by:

getValueFunction in class SATSBidder

Throws:

UnsupportedBiddingLanguageException

refreshReference

public void refreshReference(World world)

Description copied from class: SATSBidder

To prevent from creating too many identical world instances, worlds are not serialized and deserialized with the bidder
As a temporary solution, the world instance is re-added after deserialization by calling this method.

This method will be removed in a later version and be done automatically during deserialization.

Specified by:

refreshReference in class SATSBidder

See Also:

SATSBidder.refreshReference(World)

getBestBundles

public java.util.LinkedHashSet<org.marketdesignresearch.mechlib.core.Bundle> getBestBundles(org.marketdesignresearch.mechlib.core.price.Prices prices,
                                                                                            int maxNumberOfBundles,
                                                                                            boolean allowNegative)
