Class UncertainAdditiveUtilitySpace

java.lang.Object

genius.core.utility.AbstractUtilitySpace

genius.core.utility.AdditiveUtilitySpace

genius.core.utility.UncertainAdditiveUtilitySpace

All Implemented Interfaces:

UtilitySpace, java.io.Serializable

public class UncertainAdditiveUtilitySpace
extends AdditiveUtilitySpace

UncertainAdditiveUtilitySpace defines a subset of bids in the bidspace with a full ordering: bid1<=bid2<=bid3...<=bidN. N is <= the total number of bids in the space. Part of the bids may be incorrectly placed. Instead of containing these bids, this space contains an AdditiveUtilitySpace from which the N bids are generated. Usually the N bids with highest utility are taken.

Constructor to extend normal AdditiveUtilitySpace to a UncertainAdditiveUtilitySpace.

Parameters:

utilitySpace - the existing AdditiveUtilitySpace.

comparisons - the value for comparisons

errors - the value for errors

experimental - the value for experimental

Method Detail

getComparisons

public java.lang.Integer getComparisons()

Returns:

number of comparisons in the user view of this space

getErrors

public java.lang.Integer getErrors()

Returns:

number of errors in the user view of the space

isExperimental

public java.lang.Boolean isExperimental()

Returns:

true iff parties are allowed to access the underlying AdditiveUtilitySpace

loadTreeFromFile

protected boolean loadTreeFromFile(java.lang.String filename)
                            throws java.io.IOException

Overrides:

loadTreeFromFile in class AdditiveUtilitySpace

Parameters:

filename - The name of the xml file to parse.

Throws:

java.io.IOException - if error occurs, e.g. file not found

toXML

public SimpleElement toXML()
                    throws java.io.IOException

Description copied from interface: UtilitySpace

Creates an xml representation (in the form of a SimpleElements) of the utilityspace.

Specified by:

toXML in interface UtilitySpace

Overrides:

toXML in class AdditiveUtilitySpace

Returns:

A representation of this utilityspace or null when there was an error.

Throws:

java.io.IOException
