edu.cuny.cat.valuation
Class IntervalValuerGenerator

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

All Implemented Interfaces:

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

public class IntervalValuerGenerator
extends java.lang.Object
implements ValuerGenerator

Agents configured with valuation policies created by this generator will receive a unique private value from a common set of values starting at minValue and incrementing by step as each agent is assigned a valuation at agent setup time. This is useful for quickly specifying supply or demand curves with a constant "slope" (step).

Parameters

base.minvalue double >= 0 (50.0 by default)	(the minimal private value to be allocated)
base.step double >= 0 (5.0 by default)	(the amount to increase each step for next private value)

Default Base

interval_valuer
