Constructor Detail

SizeBasedUniqueRandomXOR

public SizeBasedUniqueRandomXOR(Collection<T> goods,
                                RNGSupplier rngSupplier,
                                Bidder<T> bidder)

Method Detail

getValue

protected BigDecimal getValue(Bundle<T> goods)

getBidder

public Bidder<T> getBidder()

Description copied from interface: BiddingLanguage

References back to the Bidder instance from whom this Bidding language instance was created.

Specified by:

getBidder in interface BiddingLanguage

setDefaultDistribution

public void setDefaultDistribution()

setDistribution

public void setDistribution(int meanBundleSize,
                            double standardDeviation,
                            int iterations)

Set the basic properties of this iterator. Note that the parameters are not checked for its validity and meaningfulness.

Parameters:

meanBundleSize - : The mean bundle size of the randomly generated packages. Should by greater than 0 and less than or equal to the number of goods.

standardDeviation - : The bundle size standard deviation

iterations - : The number of iterations before iterator.hasNext() returns false. Note that setting this parameter too high will result in a slow iterator and possibly cause a StackOverflowException while iterating.

iterator

public Iterator<XORValue<T>> iterator()

Throws a MissingInformationException if the method setDistribution(int, double, int) was not called before this operation.
