All Implemented Interfaces:

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

public class EquilibriumBeatingAcceptingPolicy
extends QuoteBeatingAcceptingPolicy

implements the shout-accepting rule under which a shout must be more competitive than an estimated equilibrium.

The equilibrium is estimated through some learning algorithm, e.g. sliding-window-average learning and widrowhoff learning, by training with transaction prices.

Parameters

base.delta double >= 0 (0 by default)	(an absolute amount to relax the restriction on shouts)
base.learner name of class, implementing MimicryLearner	(the learning algorithm for estimating the equilibrium price)

Default Base

equilibrium_beating_accepting
