burlap.behavior.functionapproximation.dense.PFFeatures

All Implemented Interfaces:

DenseStateFeatures

public class PFFeatures
extends java.lang.Object
implements DenseStateFeatures

Binary features that are determined from a list of PropositionalFunctions. The element for a corresponding PropositionalFunction is set to 1, when any possible binding for the PropositionalFunction is true for the input state.
