Constructor Detail

LSVMWorld

public LSVMWorld(LSVMWorldSetup worldSetup,
                 RNGSupplier rngSupplier)

Method Detail

getGrid

public LSVMGrid getGrid()

restorePopulation

public java.util.List<LSVMBidder> restorePopulation(long populationId)

Description copied from class: World

Restore serialized SATSBidder instances via population id

Specified by:

restorePopulation in class World

Parameters:

populationId - the population id

Returns:

the deserialized bidders

getLicenses

public com.google.common.collect.ImmutableList<LSVMLicense> getLicenses()

Specified by:

getLicenses in class World

Returns:

An immutable set containing all licenses.

getNumberOfGoods

public int getNumberOfGoods()

Specified by:

getNumberOfGoods in class World

refreshFieldBackReferences

public void refreshFieldBackReferences()

Description copied from class: World

Some of the members of the World (e.g. licenses) have circular references back to the world.
As the used gsonSerializer cannot handle this yet, the circular references are not serialized and have to be restored after deserialization by calling this method.

This method will be removed in a later version and the problem be solved during deserialization.

Specified by:

refreshFieldBackReferences in class World

createPopulation

public java.util.List<LSVMBidder> createPopulation(java.util.List<LSVMBidderSetup> setups,
                                                   RNGSupplier populationRNG)

isLegacyLSVM

public boolean isLegacyLSVM()

In earlier versions of SATS (earlier than 0.7.0), the original model was interpreted differently than it is today. Back then, when asking a bidder what her value is for bundle X, the synergy factor increased with any good in X. Now, the synergy factor only increases with goods which the bidder has a positive value for. This flag can be set to true in order to reproduce results of the old SATS versions.
