Constructor Detail

AdditiveUtilitySpaceFactory

public AdditiveUtilitySpaceFactory(Domain d)

Generates an simple Utility Space on the domain, with equal weights and zero values. Everything is zero-filled to already have all keys contained in the utility maps.

Method Detail

setUtility

public void setUtility(Issue i,
                       ValueDiscrete v,
                       double val)

getUtility

public double getUtility(Issue i,
                         ValueDiscrete v)

estimateUsingBidRanks

public void estimateUsingBidRanks(BidRanking r)

A simple heuristic for estimating a discrete AdditiveUtilitySpace from a BidRanking. Gives 0 points to all values occurring in the lowest ranked bid, then 1 point to all values occurring in the second lowest bid, and so on.

normalizeWeightsByMaxValues

public void normalizeWeightsByMaxValues()

getUtilitySpace

public AdditiveUtilitySpace getUtilitySpace()

Returns the utility space that has been created.
