Method Detail

setTransitionProbability

public void setTransitionProbability(java.lang.Object fromObj,
                                     java.lang.Object toObj,
                                     double prob)

Set the likelihood that toObj will follow fromObj

incTransitionProbability

public void incTransitionProbability(java.lang.Object fromObj,
                                     java.lang.Object toObj)

Increase the transition weight from fromObj to toObj by 1. Useful for building up transition states from an input sequence. If you use this, don't use setTransitionProbability(). If transition did not already exist, it is created

next

public java.lang.Object next(java.lang.Object fromObj)

Returns:

Object chosen using transition probabilities from fromObj, or null if no transition state exists

chooseUniformRandomObject

public java.lang.Object chooseUniformRandomObject()

main

public static void main(java.lang.String[] args)
