public class StimuliResponseStrategy

extends DiscreteLearnerStrategy

implements java.io.Serializable

A trading strategy that uses a stimuli-response learning algorithm, such as the Roth-Erev algorithm, to adapt its trading behaviour in successive auction rounds by using the agent's profits in the last round as a reward signal.

Parameters

base.learner classname, inherits StimuliResponseLearner

(the learning algorithm to use)
