      edu.cuny.cat.market.charging.ChargingPolicy
          edu.cuny.cat.market.charging.AdaptiveChargingPolicy

All Implemented Interfaces:

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

Direct Known Subclasses:

BestResponseChargingPolicy, MomentumChargingPolicy, ShareBalancingChargingPolicy

public abstract class AdaptiveChargingPolicy
extends ChargingPolicy

An adaptive charging policy that uses learners to determine charges..

If a learner for some type of charge is not provided, the charging becomes fixed at the initial rate.

Parameters

base.registration double	(initial charge on registration)
base.registration.learner name of class, inheriting MimicryLearner	(learner that adapts registration charge; can be null)
base.registration.scale double	(level of perturbation on registration charge)
base.information double	(initial charge on information)
base.information.learner name of class, inheriting MimicryLearner	(learner that adapts information charge; can be null)
base.information.scale double	(level of perturbation on information charge)
base.shout double	(initial charge on shout)
base.shout.learner name of class, inheriting MimicryLearner	(learner that adapts shout charge; can be null)
base.shout.scale double	(level of perturbation on shout charge)
base.transaction double	(initial charge on transaction)
base.transaction.learner name of class, inheriting MimicryLearner	(learner that adapts transaction charge; can be null)
base.transaction.scale double	(level of perturbation on transaction charge)
base.profit double [0,1]	(initial charge on profit)
base.profit.learner name of class, inheriting MimicryLearner	(learner that adapts profit charge; can be null)
base.profit.scale double	(level of perturbation on profit charge)
