edu.cuny.cat.valuation
Class RandomValuerGenerator

java.lang.Object
  edu.cuny.cat.valuation.RandomValuerGenerator

All Implemented Interfaces:

AuctionEventListener, ValuerGenerator, edu.cuny.config.param.Parameterizable, edu.cuny.obj.Resetable

Direct Known Subclasses:

DailyRandomValuerGenerator, GamelyRandomValuerGenerator

public class RandomValuerGenerator
extends java.lang.Object
implements ValuerGenerator

This valuer generator creates valuation policies in which we randomly determine our valuation across all auctions and all units at agent-initialisation time. Valuations are drawn from a certain distribution with the specified range.

Parameters

base .minvalue double >= 0	(the minimum valuation)
base .maxvalue double >=0	(the maximum valuation)
base.distribution full name of class inheriting cern.jet.random.AbstractDistribution	(the distribution used for choosing valuation, e.g. ChiSquare)

Default Base

random_valuer
