BidPoint

public BidPoint(Bid bid,
                java.lang.Double... utility)

Create a BidPoint by given the bid and the tuple of utilities for that bid.

Parameters:

bid - from which the utilities are stored.

utility - tuple of utilities of the bid.

Method Detail

hashcode of this object.

getBid

public Bid getBid()

Bid from which the utilities are represented. This bid may be null to save memory.

Returns:

bid which utilities are represented.

getUtility

public java.lang.Double getUtility(int index)

Returns the utility of the bid for the i'th agent (agent A = 0, etc.).

Parameters:

index - of the agent of which the utility should be returned.

Returns:

utility of the bid for the i'th agent.

getUtilityA

public java.lang.Double getUtilityA()

Returns the utility of the bid for agent A.

Returns:

utility for agent A.

getUtilityB

public java.lang.Double getUtilityB()

Returns the utility of the bid for agent B.

Returns:

utility for agent B.

isStrictlyDominatedBy

public boolean isStrictlyDominatedBy(BidPoint other)

Returns true if this BidPoint is strictly dominated by another BidPoint. A BidPoint is dominated when the utility of the other bid for at least one agent is higher and equal for the other agent.

Parameters:

other - BidPoint.

Returns:

true if "other" dominates "this".

getDistance

public double getDistance(BidPoint other)

Returns the distance between this BidPoint and another BidPoint. sqrt((Tx - Ox) ^ 2 + (Ty - Oy) ^ 2 + ...).

Parameters:

other - bidpoint to which the distance is calculated.

Returns:

distance to the given bidpoint.
