  de.cesr.lara.components.decision.impl.LDeliberativeChoiceComp_Probabilistic

All Implemented Interfaces:

LaraDeliberativeChoiceComponent

public class LDeliberativeChoiceComp_Probabilistic
extends Object
implements LaraDeliberativeChoiceComponent

Selects behavioural options based on a probabilistic choice mechanism. BOs are placed on a roulette wheel with the range according to their utility. The BO is selected in whose range the random number falls. IN case of negative utility sums all utility sums are shifted right by the lowest value. Eta is used as an exponent to the BO's utility that influenced the range on the roulette wheel. In case of a single BO or if (k == number of available BOs) the process is accelerated by directly choosing this BO.
