All Implemented Interfaces:

ITactic

public class DecreaseProcessingRateImpl
extends AbstractProcessingRateTactic

This class implements an IHeuristic which decreases the processing rate of hardly utilized processing resources. XXX increase or decrease processing rate by a randomized demand, e.g. normally distributed around the given parameter value?
